DATASHEET Quad, 16.5kV ESD Protected, 3.0V to 5.5V, RS-485/RS-422 Receivers ISL32173E, ISL32175E, ISL32177E, ISL32273E, ISL32275E, ISL32277E These Intersil devices are 16.5kV IEC61000-4-2 ESD Features protected, 3.0V to 5.5V powered, quad receivers for balanced communication using the RS-485 and RS-422 standards. Each receiver has low input currents (200A), so it presents a 1/4 unit load to the RS-485 bus and allows up to 128 receivers on the bus. The ISL32173E, ISL32175E, ISL32177E are high data rate receivers that operate at data rates up to 80Mbps. Their 8ns maximum propagation delay skew (tolerance) guarantees excellent part-to-part matching. The ISL32273E, ISL32275E, ISL32277E are reduced supply current versions that operate at data rates up to 20Mbps. Receiver outputs are tri-statable and incorporate a hot plug feature to keep them disabled during power-up and power-down. Versions are available with a common EN/EN (ISL32173E pinout), a two channel EN12/EN34 (ISL32175E pinout), or a vers atile individual channel enable (see Table 1). A 26% smaller footprint is available with the ISL32177E and ISL32277E QFN packages and these two devices also feature a logic supply pin (VL). The VL supply sets the switching points of the enable inputs and the receiver outputs' VOH, to levels compatible with a lower supply voltage in mixed voltage systems. Individual channel and group enable pins increase the ISL32177E and ISL32277E's flexibility. * IEC61000 ESD protection (RS-485 inputs) . . . . . . . . 16.5kV - Class 3 ESD on all other pins . . . . . . . . . . . . . . . .>8kV HBM * Wide supply range . . . . . . . . . . . . . . . . . . . . . . . . . 3.0V to 5.5V * Wide common-mode range . . . . . . . . . . . . . . . . . -7V to +12V * Low part-to-part propagation delay tolerance (ISL3217XE) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8ns (max) * Specified for +125C operation * Fail-safe open Rx inputs * 1/4 unit load allows 128 devices on the bus * Available in industry standard pinouts (ISL32173E/ ISL32175E ) and a 4x4 QFN (ISL32X77E) with added features * Logic supply pin (VL) eases operation in mixed supply systems (ISL32X77E) * High data rates. . . . . . . . . . . . . . . . up to 80Mbps or 20Mbps * Low shutdown supply current. . . . . . . . . . . . . . . . . . . . . . 60A * Tri-statable Rx outputs * 5V tolerant logic inputs when VCC = 3.3V Applications * Telecom equipment * Motor controllers/encoders * Programmable logic controllers * Industrial/process control networks FREQUENCY RECEIVER INPUT (V) VCC = 3.3V, +25C # of DEVICES = 270 80Mbps 0 -1 FIGURE 1.

All receiver outputs are enabled by driving EN high OR EN low and the outputs are all high impedance when EN is low AND EN is high (i.e., if using only the active high EN, connect EN to VCC or VL through a 1k resistor; if using only the active low EN, connect EN directly to GND). If the group enable function is not required, connect EN to VCC (or VL) through a 1k or greater resistor, or connect EN directly to GND (ISL32X73E and ISL32X77E only). - 4, 12 - EN12, EN34 Paired driver output enables, that are internally pulled high to VCC. Driving EN12 (EN34) high enables the channel 1 and 2 (3 and 4) RO outputs. Driving EN12 (EN34) low disables the channel 1 and 2 (3 and 4) outputs. If the enable function isn't required, connect EN12 and EN34 to VCC (or VL) through a 1k or greater resistor (ISL32X75E only). - - 2, 3, 16, 17 EN1, EN2, EN3, EN4 Individual receiver output enables that are internally pulled high to VCC. Forcing ENX high (along with EN high OR EN low) enables the channel X output (ROX). Driving ENX low disables the channel X output, regardless of the states of EN and EN. If the individual channel enable function isn't required, connect ENX to VCC (or VL) through a 1k or greater resistor (ISL32X77E only). - - 9 SHDNEN Low power SHDN mode enable that is internally pulled high to VCC. A high level allows the ISL32X77E to enter a low power mode when all channels are disabled. A low level prevents the device from entering the low power mode (ISL32X77E only). 3, 5, 11, 13 3, 5, 11, 13 1, 6, 13, 18 RO1, RO2, RO3, RO4 Channel X receiver output: If A - B 200mV, RO is high; If A - B -200mV, RO is low.

On devices with a VL pin powered from a separate supply, power up VCC first. - - 21 VL Logic power supply input (1.4V to VCC) that powers all the TTL/CMOS inputs and outputs (logic pins). VL sets the VIH and VIL levels of the enable and SHDNEN pins and sets the VOH level of the RO pins. Connect the VL pin to the lower voltage power supply of a logic device (e.g., UART or controller) interfacing with the ISL32X77E logic pins. If VL and VCC are different supplies, power up this supply after VCC and keep VL VCC. To minimize input current and SHDN supply current, logic pins that are strapped high externally (preferably through a 1k resistor) should connect to VCC, but they may also connect to VL (ISL32X77E only). - - 5, 14 NC No Connection Submit Document Feedback 3 Ground connection.

MEASUREMENT POINTS FIGURE 7A. TEST CIRCUIT FIGURE 7. RECEIVER ENABLE AND DISABLE TIMES Application Information RS-485 and RS-422 are differential (balanced) data transmission standards for use in long haul or noisy environments. RS-422 is a subset of RS-485, so RS-485 transceivers are also RS-422 compliant. RS-422 is a point-to-multipoint (multidrop) standard, which allows only one driver and up to 10 (assuming one unit load devices) receivers on each bus. RS-485 is a true multipoint standard, which allows up to 32 one unit load devices (any combination of drivers and receivers) on each bus. Another important advantage of RS-485 is the extended Common-Mode Range (CMR), which specifies that the driver outputs and receiver inputs withstand signals that range from +12V to -7V. RS-422 and RS-485 are intended for runs as long as 4000', so the wide CMR is necessary to handle ground potential differences, as well as voltages induced in the cable by external fields. Receiver Features These devices utilize differential receivers for maximum noise immunity and common-mode rejection. Input sensitivity is better than 200mV, as required by the RS-422 and RS-485 specifications. Receiver input resistance of 48k surpasses the RS-422 specification of 4k and is four times the RS-485 "Unit Load Submit Document Feedback 11 (UL)" requirement of 12k minimum. Thus, these products are known as "one-quarter UL" receivers and there can be up to 128 of these devices on a network while still complying with the RS-485 loading specification. Receiver inputs function with common-mode voltages as great as +9V/-7V outside the power supplies (i.e., +12V and -7V with VCC = 3.0V), making them ideal for long networks where induced voltages and ground potential differences are realistic concerns. All the receivers include a "fail-safe open" function that guarantees a high level receiver output if the receiver inputs are unconnected (floating). All receivers easily support a 20Mbps data rate and the ISL32173E, ISL32175E and ISL32177E support data rates up to 80Mbps. All receiver outputs are tri-statable, with the enable scheme varying by part type (see next section). Receiver Enable Functions All product types include functionality to allow disabling of the Rx outputs. The ISL32X73E types feature group (all four Rx) enable functions that are active high (EN) or active low (EN). Receivers enable when EN = 1, or when EN = 0 and they disable only when EN = 0 and EN = 1. The ISL32X75E versions use active high paired enable functions (EN12 and EN34) that enable (when high) or disable (when low) the corresponding pairs of Rx. All four of these enable pins have internal pull-up resistors to VCC, but FN7529.4 April 25, 2016 ISL32173E, ISL32175E, ISL32177E, ISL32273E, ISL32275E, ISL32277E unused enable pins that need to be high (e.g., EN when using the EN input for enable control, or EN12 and EN34 when using always enabled receivers) should always be connected externally to VCC. If VCC transients might exceed 7V, then inserting a series resistor between the input(s) and VCC limits the current that flows if the input's ESD protection starts conducting. 1 OF 4 CHANNELS ENX VCC VCC might not exceed the VIH of the ISL32X77E's 3.3V or 5V powered enable input. Connecting the ISL32X77E's VL pin to the power supply of the logic device (as shown in Figure 9) limits the ISL32X77E's VOH to VL and reduces its logic input switching points to values compatible with the logic device's output levels. Tailoring the logic pin input switching points and RO output levels to the supply voltage of the UART, ASIC, or controller eliminates the need for a level shifter/translator between the two ICs.

Their six enable pins allow for group, paired, or individual channel enable control. Figure 8 details the ISL32X77E's internal enable logic. To utilize a group enable function, connect all the ENX pins high and handle the EN and EN pins as described in the previous paragraph. For paired enables, connect EN and EN high (for the lowest current in SHDN mode, if SHDN is used) and tie EN1 and EN2 together and EN3 and EN4 together. For individual channel enables, again connect EN and EN high and drive the appropriate ENX (active high) for the particular channel. All six enable pins incorporate pull-up resistors to VCC, but unused enable pins of any type should be externally connected high, rather than being left floating. Connecting to VCC is the best choice, but VL may be utilized as long as SHDN power isn't a primary concern (for each VL connected input, ICC increases by (VCC - VL)/600k). If VCC or VL transients might exceed 7V, then inserting a series resistor between the input(s) and the supply limits the current that will flow if the input's ESD protection starts conducting. Wide Supply Range The ISL32X7XE design operates with a wide range of supply voltages from 3.0V to 5.5V and the receivers meet the RS-485 specs for that full supply voltage range. 5.5V TOLERANT LOGIC PINS Logic input pins (enables, SHDNEN) contain no ESD nor parasitic diodes to VCC (nor to VL), so they withstand input voltages exceeding 5.5V regardless of the VCC and VL voltages (see Figure 11 on page 14). Logic Supply (VL Pin, ISL32177E and ISL32277E) Note: If powered from separate supplies, power up VCC before powering up the VL supply. The ISL32177E and ISL32277E include a VL pin that powers the logic inputs (enables, SHDNEN) and the RO outputs. These pins interface with "logic" devices such as UARTs, ASICs and controllers and today most of these devices use power supplies significantly lower than 3.3V. Thus, a 5V or 3.3V RO output level from an ISL32X77E IC might seriously overdrive and damage the logic device input (Figure 9).

USING VL PIN TO ADJUST LOGIC LEVELS VL can be anywhere from VCC down to 1.4V, but the data rate drops off dramatically below VL = 1.6V. Table 2 indicates typical VIH and VIL values (applicable to both speed grades) for various VL settings and also lists the ISL32177E's typical data rate versus VL. The ISL32277E typically runs at 20Mbps for VL 1.6V and drops to 10Mbps to 15Mbps at VL=1.4V. Prop delays, skews and transition times increase at lower VL, as shown in Figures 22 through 34. TABLE 2. TYPICAL VIH, VIL AND DATA RATE vs VL FOR VCC = 3.3V OR 5V VL (V) VIH (V) VIL (V) ISL32177E DATA RATE (Mbps) 1.4 0.55 0.5 25 1.6 0.6 0.55 50 1.8 0.8 0.7 65 2.3 1 0.9 70 2.7 1.1 1 75 3.3 1.3 1.2 80 FN7529.4 April 25, 2016 ISL32173E, ISL32175E, ISL32177E, ISL32273E, ISL32275E, ISL32277E Neglecting the RO IOH currents, the quiescent VL supply current (IL) is typically less than 1A for enable input voltages at ground or VL, as shown in Figure 11 on page 14. Enable pin pull-up resistors connect to VCC, so the current due to a low enable input adds to ICC rather than to IL. Hot Plug Function When a piece of equipment powers up, there is a period of time where the processor or ASIC driving the RS-485 control lines (EN, EN, ENX) is unable to ensure that the RS-485 Rx outputs are kept disabled. If the equipment is connected to the bus, a receiver activating prematurely during power up may generate RO transitions that could cause interrupts. To avoid this scenario, this family incorporates a "Hot Plug" function. During power up, circuitry monitoring VCC ensures that the Rx outputs remain disabled for a period of time, regardless of the state of the enables. This gives the processor/ASIC a chance to stabilize and drive the RS-485 control lines to the proper states. ESD Protection All pins on these devices include class 3 (>8kV) Human Body Model (HBM) ESD protection structures, but the RS-485 pins (receiver inputs) incorporate advanced structures allowing them to survive ESD events in excess of 15kV HBM and 16.5kV IEC 61000-4-2. The RS-485 pins are particularly vulnerable to ESD damage because they typically connect to an exposed port on the exterior of the finished product. Simply touching the port pins, or connecting a cable, can cause an ESD event that might destroy unprotected ICs. These new ESD structures protect the device whether or not it is powered up and without degrading the RS-485 common-mode range of -7V to +12V. This built-in ESD protection eliminates the need for board level protection structures (e.g., transient suppression diodes) and the associated, undesirable capacitive load they present. Data Rate, Cables and Terminations The RS-485 and RS-422 are intended for network lengths up to 4000', but the maximum system data rate decreases as the transmission length increases. Networks operating at 80Mbps are limited to lengths much less than 100' (30m), while a 20Mbps version can operate at full data rates with lengths up to 200' (60m). Any of these ICs may be used at slower data rates over longer cables, but there are some limitations for the 80Mbps versions. The 80Mbps Rx is optimized for high speed operation, so its output may glitch if the Rx input differential transition times are too slow. Keeping the transition times below 500ns, which equates to a Tx driving a 1000' (305m) CAT 5 cable, yields excellent performance over the full operating temperature range. Twisted pair is the cable of choice for RS-485 and RS-422 networks. Twisted pair cables tend to pick up noise and other electromagnetically induced voltages as common-mode signals, which are effectively rejected by the differential receivers in these ICs. When using these receivers, proper termination is imperative to minimize reflections. Short networks using slew rate limited transmitters need not be terminated, but terminations are recommended unless power dissipation is an overriding concern. In point-to-point, or point-to-multipoint (single driver on a bus with multiple receivers) networks, the main cable should be terminated in its characteristic impedance (typically 120) at the end farthest from the driver. In multireceiver applications, stubs connecting receivers to the main cable should be kept as short as possible. Multipoint (multidriver) systems require that the main cable be terminated in its characteristic impedance at both ends. Stubs connecting a transmitter or receiver to the main cable should be kept as short as possible. IEC 61000-4-2 Testing Low Power Shutdown Mode The IEC 61000 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-485 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-485 pins allows the design of equipment meeting level 4 criteria without the need for additional board level protection on the RS-485 port. These BiCMOS receivers all use a fraction of the power required by their bipolar counterparts, but they also include a Shutdown (SHDN) feature that reduces the already low quiescent ICC to a microamp trickle. These devices enter shutdown only when all four receivers disable (see "Truth Tables" on page 5) for at least 600ns. The ISL32X73E types enter SHDN whenever EN is low and EN is high. ISL32X75E types enter SHDN only if both EN12 and EN34 are low. Note that the ISL32X75E enable times increase significantly when enabling from the SHDN condition. AIR-GAP DISCHARGE TEST METHOD For this 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 approach speed, humidity, temperature, etc., so it is difficult to obtain repeatable results. The A and B RS-485 pins withstand 16.5kV air-gap discharges. CONTACT DISCHARGE TEST METHOD During the contact discharge test, the probe contacts the tested pin before the probe tip is energized, thereby eliminating the variables associated with the air-gap discharge. These Quad receivers survive 8kV contact discharges on the RS-485 pins. Submit Document Feedback 13 The ISL32X77E enter the low power SHDN mode if SHDNEN is high and if all four Rx are disabled for at least 600ns. This is accomplished by driving EN low and EN high, or by driving all four ENX inputs low. Enable times increase if the IC was in SHDN, so if enable time is more important than SHDN supply current, tying the SHDNEN pin low defeats the low power SHDN feature. In this mode, the supply current drops to 1mA to 2mA when all four Rx are disabled, but the enable time of any Rx remains below 200ns. Remember that all enable pins have pull-up resistors on them, so each pin that is low during SHDN adds up to 15A to the SHDN supply current. The SHDN supply current entries in the "Electrical Specifications" table on page 8 include the resistor currents of the pins indicated to be in the low state.
