Datasheet ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, ICL3243E 15kV ESD Protected, +3V to +5.5V, 1A, 250kbps, RS-232 Transmitters/Receivers The ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, and ICL3243E are 3.0V to 5.5V powered RS-232 transmitters/receivers that meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. Additionally, they provide 15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are notebook and laptop computers in which the low operational power consumption and even lower standby power consumption is critical. Efficient on-chip charge pumps, coupled with manual and automatic power-down functions (except for the ICL3232E), reduce the standby supply current to a 1A trickle. Small footprint packaging and the use of small, low value capacitors ensure board space savings. Data rates greater than 250kbps are ensured at worst case load conditions. This family is fully compatible with 3.3V-only systems, mixed 3.3V and 5.0V systems, and 5.0V-only systems. Features * ESD protection for RS-232 I/O pins to 15kV (IEC61000) * Drop-in replacements for the MAX3221E, MAX3222E, MAX3223E, MAX3232E, MAX3241E, MAX3243E, and SP3243E * The ICL3221E is a low-power, pin-compatible upgrade for the 5V MAX221E * The ICL3222E is a low-power, pin-compatible upgrade for the 5V MAX242E and SP312E * The ICL3232E is a low-power upgrade for the HIN232E, ICL232, and pin-compatible competitor devices * RS-232 compatible with VCC = 2.7V * Meets EIA/TIA-232 and V.28/V.24 specifications at 3V * Latch-up free The ICL324XE are 3-driver, 5-receiver devices that provide a complete serial port suitable for laptop or notebook computers. Both devices also include noninverting always-active receivers for "wake-up" capability. * On-chip voltage converters require only four external 0.1F capacitors at VCC = 3.3V The ICL3221E, ICL3223E, and ICL3243E feature an automatic power-down function that powers down the on-chip power supply and driver circuits. Power-down occurs when an attached peripheral device is shut off or the RS-232 cable is removed, which conserves system power automatically without changes to the hardware or operating system. These devices power up again when a valid RS-232 voltage is applied to any receiver input. * Receiver hysteresis for improved noise immunity Table 1 on page 2 summarizes the features of the devices represented by this datasheet, and Application Note AN9863 summarizes the features of each device in the ICL32xxE 3V family.

Application Information Application Information The ICL32xxE interface ICs operate from a single +3V to +5.5V supply, ensure a 250kbps minimum data rate, require only four small external 0.1F capacitors, feature low power consumption, and meet all ElA RS-232C and V.28 specifications. 4.1 Charge-Pump The ICL32xxE family uses regulated on-chip dual charge-pumps as voltage doublers, and voltage inverters to generate 5.5V transmitter supplies from a VCC supply as low as 3.0V. The charge-pumps allow the devices to maintain RS-232 compliant output levels over the 10% tolerance range of 3.3V powered systems. The efficient on-chip power supplies require only four small external 0.1F capacitors for the voltage doubler and inverter functions at VCC = 3.3V. See "Capacitor Selection" on page 21 and Table 6 on page 21 for capacitor recommendations for other operating conditions. The charge-pumps operate discontinuously (they turn off as soon as the V+ and V- supplies are pumped up to the nominal values) and provide significant power savings. 4.1.1 Charge-Pump Abs Max Ratings These 3V to 5V RS-232 transceivers have been fully characterized for 3.0V to 3.6V operation, and at critical points for 4.5V to 5.5V operation. Furthermore, load conditions were favorable using static logic states only. The specified maximum values for V+ and V- are +7V and -7V, respectively.

Table 4. 4.2 New Measured Withstanding Voltages V+, V- to Ground 13V V+ to V- 20V Transmitters The transmitters are proprietary, low dropout, inverting drivers that translate TTL/CMOS inputs to EIA/TIA-232 output levels. The transmitters are coupled with the on-chip 5.5V supplies and deliver true RS-232 levels across a wide range of single supply system voltages. Except for the ICL3232E, all transmitter outputs disable and assume a high impedance state when the device enters the power-down mode (see Table 5 on page 18). The outputs can be driven to 12V when disabled. All devices operate at a 250kbps data rate for full load conditions (3k and 1000pF), VCC 3.0V, with one transmitter operating at full speed. Under more typical conditions of VCC 3.3V, RL = 3k, and CL = 250pF, one transmitter easily operates at 900kbps. The transmitter inputs float if left unconnected and can increase ICC. Connect unused inputs to GND for the best performance. 4.3 Receivers All the ICL32xxE devices except for the ICL3232E contain standard inverting receivers that three-state from the EN or FORCEOFF control lines. The two ICL324XE devices include noninverting (monitor) receivers (denoted by the ROUTB label) that are always active, regardless of the state of any control lines. All the receivers convert RS-232 signals to CMOS output levels and accept inputs up to 25V while presenting the required 3k to 7k input impedance (see Figure 7) even if the power is off (VCC = 0V). The receivers' Schmitt trigger input stage uses hysteresis to increase noise immunity and decrease errors due to slow input signal transitions.

Inverting Receiver Connections The ICL3221E, ICL3222E, ICL3223E, and ICL3241E inverting receivers disable only when EN is driven high. The ICL3243E receiver disables during forced (manual) power-down, but not during automatic power-down (see Table 5 on page 18). The ICL3241E and ICL3243E monitor receivers remain active even during manual power-down and forced receiver disable, which makes them extremely useful for Ring Indicator monitoring. Standard receivers driving powered down peripherals must be disabled to prevent current flow through the peripheral's protection diodes (see Figures 8 and 9). When disabled, the receivers cannot be used for wake up functions, but the corresponding monitor receiver can be dedicated to this task, as shown in Figure 9.

Application Information Low Power Operation These 3V devices require a nominal supply current of 0.3mA, even at VCC = 5.5V, during normal operation (not in power-down mode). This current is considerably less than the 5mA to 11mA current required by comparable 5V RS-232 devices and allows you to reduce system power simply by switching to this family. 4.5 Power-Down Functionality (Except ICL3232E) The already low current requirement drops significantly when the device enters power-down mode. In power-down, the supply current drops to 1A because the on-chip charge pump turns off (V+ collapses to VCC and V- collapses to GND), and the transmitter outputs three-state. Inverting receiver outputs may disable in power-down; see Table 5 for details. This micro-power mode makes these devices ideal for battery powered and portable applications. 4.5.1 Software Controlled (Manual) Power-Down Most devices in the ICL32xxE family provide pins that allow you to force the IC into the low power standby state. On the ICL3222E and ICL3241E, the power-down control is a simple shutdown (SHDN) pin. Driving this pin high enables normal operation, and driving it low forces the IC into its power-down state. Connect SHDN to VCC if the power-down function is not needed. Note that all the receiver outputs remain enabled during shutdown (see Table 5). For the lowest power consumption during power-down, the receivers should also be disabled by driving the EN input high (see "Receiver ENABLE Control (ICL3221E, ICL3222E, ICL3223E, and ICL3241E Only)" on page 21 and Figures 8 and 9). The ICL3221E, ICL3223E, and ICL3243E use a two pin approach in which the FORCEON and FORCEOFF inputs determine the IC's mode. For always enabled operation, FORCEON and FORCEOFF are both strapped high. Under logic or software control, only the FORCEOFF input needs to be driven to switch between active and power-down modes. The FORCEON state is not critical because FORCEOFF overrides FORCEON. However, if strictly manual control over power-down is needed, you must strap FORCEON high to disable the automatic power-down circuitry. The ICL3243E inverting (standard) receiver outputs also disable when the device is in manual power-down, which eliminates the possible current path through a shutdown peripheral's input protection diode (see Figures 8 and 9).

Applies only to the ICL3241E and ICL3243E. 4.5.2 INVALID Output The INVALID output always indicates whether a valid RS-232 signal is present at any of the receiver inputs (see Table 5) and provides an easy way to determine when the interface block should power down. If an interface cable is disconnected and all the receiver inputs are floating (but pulled to GND by the internal receiver pull down resistors), the INVALID logic detects the invalid levels and drives the output low. The power management logic then uses this indicator to power down the interface block. Reconnecting the cable restores valid levels at the receiver inputs, INVALID switches high, and the power management logic wakes up the interface block. INVALID can also indicate the DTR or RING INDICATOR signal as long as the other receiver inputs are floating or driven to GND (as in the case of a powered down driver). Connecting FORCEOFF and FORCEON together disables the automatic power-down feature and enables them to function as a manual SHUTDOWN input (see Figure 10).

Connections For Manual Power-Down When no Valid Receiver Signals are Present With any of the control schemes, the time required to exit power-down and resume transmission is 100s. A mouse or other application may need more time to wake up from shutdown. If automatic power-down is used, the RS-232 device reenters power-down if valid receiver levels are not reestablished within 30s of the ICL32xxE FN4910 Rev.24.00 May 30, 2019 Page 19 of 39 ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, ICL3243E 4. Application Information powering up. Figure 11 shows a circuit that prevents the ICL32xxE from initiating automatic power-down for 100ms after powering up.

Circuit to Prevent Auto Power-Down For 100ms After Forced Power-Up 4.5.3 Automatic Power-Down (ICL3221E, ICL3223E, and ICL3243E Only) Even greater power savings are available by using the ICL3221E, ICL3223E, or ICL3243E's automatic power-down function. When no valid RS-232 voltages are sensed on any receiver input for 30s (see Figure 12), the charge-pump and transmitters power down and reduce the supply current to 1A. Invalid receiver levels occur whenever the driving peripheral's outputs are shut off (powered down) or when the RS-232 interface cable is disconnected. The ICL32xxE powers back up whenever it detects a valid RS-232 voltage level on any receiver input. The automatic power-down feature provides additional system power savings without changes to the existing operating system. 2.7V Valid RS-232 Level - ICL32xxE is Active Indeterminate - Power-down may or may not occur 0.3V Invalid Level - Power-down occurs after 30s -0.3V Indeterminate - Power-down may or may not occur -2.7V Valid RS-232 Level - ICL32xxE is Active Figure 12. Definition of Valid RS-232 Receiver Levels Automatic power-down operates when the FORCEON input is low and the FORCEOFF input is high. Tying FORCEON high disables automatic power-down, but manual power-down is always available with the overriding FORCEOFF input. Table 5 on page 18 summarizes the automatic power-down functionality. Devices with the automatic power-down feature include an INVALID output signal that switches low to indicate that invalid levels have persisted on all of the receiver inputs for more than 30s (see Figure 13). INVALID switches high 1s after detecting a valid RS-232 level on a receiver input. INVALID operates in all modes (forced or automatic power-down, or forced on), so it is also useful for systems employing manual power-down circuitry. When automatic power-down is used, INVALID = 0 indicates that the ICL32xxE is in power-down mode. The time to recover from automatic power-down mode is typically 100s.

Automatic Power-Down and INVALID Timing Diagrams 4.6 Receiver ENABLE Control (ICL3221E, ICL3222E, ICL3223E, and ICL3241E Only) The ICL3221E, ICL3222E, ICL3223E, and ICL3241E also feature an EN input to control the receiver outputs. Driving EN high disables all the inverting (standard) receiver outputs and places them in a high impedance state. The high impedance state is useful for eliminating supply current, due to a receiver output forward biasing the protection diode when driving the input of a powered down (VCC = GND) peripheral (see Figure 8 on page 17). The enable input has no effect on transmitter or monitor (ROUTB) outputs. 4.7 Capacitor Selection The charge-pumps require 0.1F capacitors for 3.3V operation. For other supply voltages, see Table 6 for capacitor values. Do not use values smaller than those listed in Table 6. Increasing the capacitor values (by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4 can be increased without increasing C1's value; however, do not increase C1 without also increasing C2, C3, and C4 to maintain the proper ratios (C1 to the other capacitors). When using minimum required capacitor values, make sure that capacitor values do not degrade excessively with temperature. If in doubt, use capacitors with a larger nominal value. The capacitor's Equivalent Series Resistance (ESR) usually rises at low temperatures and it influences the amount of ripple on V+ and V-. Table 6. 4.8 Required Capacitor ValueS VCC (V) C1 (F) C2, C3, C4 (F) 3.0 to 3.6 0.1 0.1 4.5 to 5.5 0.047 0.33 3.0 to 5.5 0.1 0.47 Power Supply Decoupling In most circumstances, a 0.1F bypass capacitor is adequate. In applications that are particularly sensitive to power supply noise, decouple VCC to ground with a capacitor of the same value as the charge-pump capacitor C1. Connect the bypass capacitor as close as possible to the IC. 4.9 Operation Down to 2.7V The ICL32xxE transmitter outputs meet RS-562 levels (3.7V) at full data rate, with VCC as low as 2.7V. RS-562 levels typically ensure interoperability with RS-232 devices. FN4910 Rev.24.00 May 30, 2019 Page 21 of 39 ICL3221E, ICL3222E, ICL3223E, ICL3232E, ICL3241E, ICL3243E 4.10 4. Application Information Transmitter Outputs when Exiting Power-Down Figure 14 shows the response of two transmitter outputs when exiting power-down mode. As they activate, the two transmitter outputs properly go to opposite RS-232 levels, with no glitching, ringing, or undesirable transients. Each transmitter is loaded with 3k in parallel with 2500pF. Note that the transmitters enable only when the magnitude of the supplies exceeds approximately 3V. 5V/Div FORCEOFF T1 2V/Div T2 VCC = +3.3V C1 - C4 = 0.1F Time (20s/Div) Figure 14.

The on-chip switching regulator ensures the transmitters supply at least 5V during worst case conditions (15mA for paralleled V+ transmitters, 7.3mA for a single V- transmitter).

Application Information Interconnection with 3V and 5V Logic The ICL32Exx devices directly interface with 5V CMOS and TTL logic families. The AC, HC, and CD4000 outputs can drive ICL32Exx inputs with the ICL32Exx at 3.3V and the logic supply at 5V, but ICL32Exx outputs do not reach the minimum VIH for these logic families. See Table 7.

ICL32XX outputs are incompatible with AC, HC, and CD4000 CMOS inputs Pin-Compatible Replacements for 5V Devices The ICL3221E, ICL3222E, and ICL3232E are pin-compatible with existing 5V RS-232 transceivers. See "Features" on page 1 for more information. The pin compatibility coupled with the low ICC and wide operating supply range make the ICL32xxE potential lower power, higher performance drop-in replacements for existing 5V applications. The ICL32xxE works in most 5V applications as long as the 5V RS-232 output swings are acceptable and transmitter input pull-up resistors are not required. When replacing a device in an existing 5V application, you can terminate C3 to VCC as shown in the "Typical Operating Circuits" on page 4. If possible, terminate C3 to GND for slightly better performance.

The RS-232 pins are particularly vulnerable to ESD damage because they typically connect to an exposed port on the exterior of the finished product. Touching the port pins or connecting a cable, can cause an ESD event that might destroy unprotected ICs. The ESD structures protect the device whether or not it is powered up, protect without allowing any latch-up mechanism to activate, and do not interfere with RS-232 signals as large as 25V. 5.1 Human Body Model (HBM) Testing This test method emulates the ESD event delivered to an IC during human handling. The tester delivers the charge through a 1.5k current limiting resistor and makes the test less severe than the IEC61000 test, which uses a 330 limiting resistor. The HBM method determines an IC's ability to withstand the ESD transients typically present during handling and manufacturing. Due to the random nature of these events, each pin is tested with respect to all other pins. The RS-232 pins on "E" family devices can withstand HBM ESD events to 15kV. 5.2 IEC61000-4-2 Testing The IEC61000 test method applies to finished equipment rather than to an individual IC. Therefore, the pins most likely to suffer an ESD event are those that are exposed to the outside world (the RS-232 pins in this case), and the IC is tested in its typical application configuration (power applied) rather than testing each pin-to-pin combination. The lower current limiting resistor coupled with the larger charge storage capacitor yields a test that is much more severe than the HBM test. The extra ESD protection built into this device's RS-232 pins allows the design of equipment meeting level 4 criteria without the need for additional board level protection on the RS-232 port. 5.3 Air-Gap Discharge Test Method For the air-gap discharge test method, a charged probe tip moves toward the IC pin until the voltage arcs to it. The current waveform delivered to the IC pin depends on factors such as approach speed, humidity, and temperature, so it is difficult to obtain repeatable results. The "E" device RS-232 pins withstand 15kV air-gap discharges. 5.4 Contact Discharge Test Method During the contact discharge test, the probe contacts the tested pin before the probe tip is energized and eliminates the variables associated with the air-gap discharge. The test is more repeatable and predictable, but equipment limits prevent testing devices at voltages higher than 8kV. All "E" family devices survive 8kV contact discharges on the RS-232 pins.
