60V Fault Protected, 5V, RS-485/RS-422 Transceivers with 25V Common Mode Range ISL31490E, ISL31491E, ISL31492E, ISL31493E, ISL31495E, ISL31496E, ISL31498E The ISL31490E, ISL31491E, ISL31492E, ISL31493E, Features ISL31495E, ISL31496E, ISL31498E are fault protected, 5V powered, differential transceivers that exceed the RS-485 and RS-422 standards for balanced communication. The RS-485 transceiver pins (driver outputs and receiver inputs) are protected against faults up to 60V. Additionally, the extended common mode range allows these transceivers to operate in environments with common mode voltages up to 25V (>2x the RS-485 requirement), making this RS-485 family one of the most robust on the market. Transmitters deliver an exceptional 2.5V (typical) differential output voltage into the RS-485 specified 54 load. This yields better noise immunity than standard RS-485 ICs, or allows up to six 120 terminations in star network topologies. * Fault Protected RS-485 Bus Pins . . . . . . . . . . . . . .

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. To allow for multipoint operation, the RS-485 specification requires that drivers must handle bus contention without sustaining any damage. The RS-485/RS-422 driver is a differential output device that delivers at least 1.5V across a 54 load (RS-485), and at least 2.4V across a 100 load (RS-422). The drivers feature low propagation delay skew to maximize bit width, and to minimize EMI, and all drivers are three-statable via the active high DE input. 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', thus the wide CMR is necessary to handle ground potential differences, as well as voltages induced in the cable by external fields. High Overvoltage (Fault) Protection Increases ruggedness The ISL3149xE is a family of ruggedized RS-485 transceivers that improves on the RS-485 basic requirements, and therefore increases system reliability. The CMR increases to 25V, while the RS-485 bus pins (receiver inputs and driver outputs) include fault protection against voltages and transients up to 60V. Additionally, larger than required differential output voltages (VOD) increase noise immunity. The 60V (referenced to the IC GND) fault protection on the RS-485 pins, makes these transceivers some of the most rugged on the market. This level of protection makes the ISL3149xE perfect for applications where power (e.g., 24V and 48V supplies) must be routed in the conduit with the data lines, or for outdoor applications where large transients are likely to occur. When power is routed with the data lines, even a momentary short between the supply and data lines will destroy an unprotected device. The 60V fault levels of this family are at least five times higher than the levels specified for standard RS-485 ICs. The ISL3149xE protection is active whether the Tx is enabled or disabled, and even if the IC is powered down. Receiver (Rx) Features These devices utilize a differential input receiver 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 (load) current surpasses the RS-422 specification of 3mA, and is four times lower than the RS-485 "Unit Load (UL)" requirement of 1mA maximum. Thus, these products are known as "one-quarter UL" transceivers, and there can be up to 128 of these devices on a network while still complying with the RS-485 loading specification. The 250kbps and 1Mbps driver outputs are slew rate limited to minimize EMI, and to minimize reflections in unterminated or improperly terminated networks. Outputs of the ISL31496E and ISL31498E drivers are not limited, thus faster output transition times allow data rates of at least 15Mbps. Note: The available smaller pitch packages (e.g., MSOP and TDFN) may not meet the creepage and clearance (C&C) requirements for 60V levels. The user is advised to determine his C&C requirements before selecting a package type. If transients or voltages (including overshoots and ringing) greater than 60V are possible, then additional external protection is required. Widest Common Mode Voltage (CMV) Tolerance Improves Operating Range Rx outputs feature high drive levels (typically 22mA @ VOL = 1V) to ease the design of optically coupled isolated interfaces. RS-485 networks operating in industrial complexes, or over long distances, are susceptible to large CMV variations. Either of these operating environments may suffer from large node-to-node ground potential differences, or CMV pickup from external electromagnetic sources, and devices with only the minimum required +12V to -7V CMR may malfunction. The ISL3149xE's extended 25V CMR is the widest available, allowing operation in environments that would overwhelm lesser transceivers. Additionally, the Rx will not phase invert (erroneously change state) even with CMVs of 40V, or differential voltages as large as 40V. Receivers easily meet the data rates supported by the corresponding driver, and all receiver outputs are three-statable via the active low RE input (except on the ISL31491E). High VOD Improves Noise Immunity and Flexibility The Rx functions with common mode voltages as great as 25V, making them ideal for industrial, or long networks where induced voltages are a realistic concern. All the receivers include a "full fail-safe" function that guarantees a high level receiver output if the receiver inputs are unconnected (floating), shorted together, or connected to a terminated bus with all the transmitters disabled (i.e., an idle bus). The Rx in the 250kbps and 1Mbps versions include noise filtering circuitry to reject high frequency signals. The 1Mbps version typically rejects pulses narrower than 50ns (equivalent to 20Mbps), while the 250kbps Rx rejects pulses below 150ns (6.7Mbps). 13 The ISL3149xE driver design delivers larger differential output voltages (VOD) than the RS-485 standard requires, or than most RS-485 transmitters can deliver. The typical 2.5V VOD provides more noise immunity than networks built using many other transceivers. FN7637.1 December 22, 2011 ISL31490E, ISL31491E, ISL31492E, ISL31493E, ISL31495E, Another advantage of the large VOD is the ability to drive more than two bus terminations, which allows for utilizing the ISL3149xE in "star" and other multi-terminated, nonstandard network topologies. Figure 10 details the transmitter's VOD vs IOUT characteristic, and includes load lines for four (30) and six (20) 120 terminations. Figure 10 shows that the driver typically delivers 1.3V into six terminations, and the "Electrical Specification" table guarantees a VOD of 0.8V at 21 over the full temperature range. The RS-485 standard requires a minimum 1.5V VOD into two terminations, but the ISL3149xE deliver RS-485 voltage levels with 2x to 3x the number of terminations. better quality cables (e.g., 22 AWG) may allow increased transmission distance. Hot Plug Function In point-to-point, or point-to-multipoint (single driver on bus like RS-422) networks, the main cable should be terminated in its characteristic impedance (typically 120) at the end farthest from the driver. In multi-receiver applications, stubs connecting receivers to the main cable should be kept as short as possible. Multipoint (multi-driver) systems require that the main cable be terminated in its characteristic impedance at both ends. Stubs connecting a transceiver to the main cable should be kept as short as possible. When a piece of equipment powers up, there is a period of time where the processor or ASIC driving the RS-485 control lines (DE, RE) is unable to ensure that the RS-485 Tx and Rx outputs are kept disabled. If the equipment is connected to the bus, a driver activating prematurely during power-up may crash the bus. To avoid this scenario, the ISL3149xE devices incorporate a "Hot Plug" function. Circuitry monitoring VCC ensures that, during powerup and power-down, the Tx and Rx outputs remain disabled, regardless of the state of DE and RE, if VCC is less than 3.5V. This gives the processor/ASIC a chance to stabilize and drive the RS-485 control lines to the proper states. Figure 9 illustrates the power-up and power-down performance of the ISL3149xE compared to an RS485 IC without the Hot Plug feature.

HOT PLUG PERFORMANCE (ISL3149xE) vs ISL83088E WITHOUT HOT PLUG CIRCUITRY Twisted pair is the cable of choice for RS-485/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. Proper termination is imperative, when using the 15Mbps devices, to minimize reflections. Short networks using the 250kbps versions need not be terminated, however, terminations are recommended unless power dissipation is an overriding concern. Built-In Driver Overload Protection As stated previously, the RS-485 specification requires that drivers survive worst case bus contentions undamaged. These transceivers meet this requirement via driver output short circuit current limits, and on-chip thermal shutdown circuitry. The driver output stages incorporate a double foldback short circuit current limiting scheme which ensures that the output current never exceeds the RS-485 specification, even at the common mode and fault condition voltage range extremes. The first foldback current level (70mA) is set to ensure that the driver never folds back when driving loads with common mode voltages up to 25V. The very low second foldback current setting (9mA) minimizes power dissipation if the Tx is enabled when a fault occurs. In the event of a major short circuit condition, devices also include a thermal shutdown feature that disables the drivers whenever the die temperature becomes excessive. This eliminates the power dissipation, allowing the die to cool. The drivers automatically re-enable after the die temperature drops about +15C. If the contention persists, the thermal shutdown/re-enable cycle repeats until the fault is cleared. Receivers stay operational during thermal shutdown. Data Rate, Cables, and Terminations Low Power Shutdown Mode RS-485/RS-422 are intended for network lengths up to 4000', but the maximum system data rate decreases as the transmission length increases. Devices operating at 15Mbps may be used at lengths up to 150' (46m), but the distance can be increased to 328' (100m) by operating at 10Mbps. The 1Mbps versions can operate at full data rates with lengths up to 800' (244m). Jitter is the limiting parameter at these faster data rates, so employing encoded data streams (e.g., Manchester coded or Return-to-Zero) may allow increased transmission distances. The slow versions can operate at 115kbps, or less, at the full 4000' (1220m) distance, or at 250kbps for lengths up to 3000' (915m). DC cable attenuation is the limiting parameter, so using These CMOS transceivers all use a fraction of the power required by competitive devices, but they also include a shutdown feature that reduces the already low quiescent ICC to a 10A trickle. These devices enter shutdown whenever the receiver and driver are simultaneously disabled (RE = VCC and DE = GND) for a period of at least 600ns. Disabling both the driver and the receiver for less than 60ns guarantees that the transceiver will not enter shutdown. 14 Note that receiver and driver enable times increase when the transceiver enables from shutdown. Refer to Notes 13, 14, 15, 16 and 17, at the end of the "Electrical Specification" table on page 10, for more information.
