16.5kV ESD (IEC61000-4-2) Protected, Large Output Swing, 5V, Full Fail-Safe, 1/8 Unit Load, RS-485/RS-422 Transceivers
The ISL315XE are BiCMOS, IEC61000 ESD protected, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output and receiver input is protected against 16.5kV ESD strikes without latch-up. The ISL315XE transmitters all deliver exceptional differential output voltages (2.4V min), into the RS-485 required 54 load, for better noise immunity or to allow up to eight 120 terminations in "star" or other non-standard bus topologies. These devices have very low bus currents (+125A/-75A), so they present a true "1/8 unit load" to the RS-485 bus. This allows up to 256 transceivers on the network without violating the RS-485 specification's 32 unit load maximum, and without using repeaters. Receiver (Rx) inputs feature a "Full Fail-Safe" design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or on a terminated but undriven bus. Rx outputs feature high drive levels - typically 28mA @ VOL = 1V (to ease the design of optocoupled isolated interfaces). The ISL3150E, ISL3152E, ISL3153E, ISL3155E utilize slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications. Hot Plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state until the power supply has stabilized, and the Tx outputs are fully short circuit protected. The ISL3150E, ISL3153E, ISL3156E are configured for full duplex applications. The half duplex versions multiplex the Rx inputs and Tx outputs to allow transceivers with output disable functions in 8 Ld packages.

All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise specified. 5. Supply current specification is valid for loaded drivers when DE = 0V. 6. Applies to peak current. See "Typical Performance Curves" for more information. 7. Keep RE = 0 to prevent the device from entering SHDN. 8. The RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN. 9. Transceivers are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 60ns, the parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are guaranteed to have entered shutdown. See "Low-Power Shutdown Mode" section. 10. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN. 11. Set the RE signal high time >600ns to ensure that the device enters SHDN. 12. Guaranteed by characterization but not tested. 13.

ISL3150E, ISL3152E, ISL3153E, ISL3155E, ISL3156E, ISL3158E Application Information
RS-485 and RS-422 are differential (balanced) data transmission standards used for 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 pointto-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 spec requires that drivers must handle bus contention without sustaining any damage. 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. The 115kbps and 1Mbps driver outputs are slew rate limited to minimize EMI, and to minimize reflections in unterminated or improperly terminated networks. Outputs of the ISL3156Eand ISL3158E drivers are not limited, so faster output transition times allow data rates of at least 20Mbps High VOD Improves Noise Immunity and Flexibility The ISL315XE driver design delivers larger differential output voltages (VOD) than the RS-485 standard requires, or than most RS-485 transmitters can deliver. The minimum 2.4V VOD guarantees at least 900mV more noise immunity than networks built using standard 1.5V VOD transmitters. Another advantage of the large VOD is the ability to drive more than two bus terminations, which allows for utilizing the ISL315XE in "star" and other multi-terminated, "nonstandard" network topologies. Figure 8, details the transmitter's VOD vs. IOUT characteristic, and includes load lines for six (20) and eight (15) 120 terminations. The figure shows that the driver typically delivers 1.65/1.5V into 6/8 terminations, even at the worst case temperature of +85C.The RS-485 standard requires a minimum 1.5V VOD into two terminations, but the ISL315XE delivers RS-485 voltage levels with 3X to 4X the number of terminations.
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. Rx outputs feature high drive levels - typically 28mA @ VOL = 1V (to ease the design of optically coupled isolated interfaces). Receiver input resistance of 96k surpasses the RS-422 spec of 4k, and is eight times the RS-485 "Unit Load (UL)" requirement of 12k minimum. Thus, these products are known as "one-eighth UL" transceivers, and there can be up to 256 of these devices on a network while still complying with the RS-485 loading spec. Rx inputs function with common mode voltages as great as 7V outside the power supplies (i.e., +12V and -7V), making them ideal for 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. Receivers easily meet the data rates supported by the corresponding driver, and all receiver outputs are threestatable via the active low RE input.
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 (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 ISL315XE devices incorporate a "Hot Plug" function. Circuitry monitoring VCC ensures that, during power up and power down, the Tx and Rx outputs remain disabled, regardless of the state of DE and RE, if VCC is less than ~3.4V. This gives the processor/ASIC a chance to stabilize and drive the RS-485 control lines to the proper states.

Driver (Tx) Features
The RS-485/422 driver is a differential output device that delivers at least 2.4V across a 54 load (RS-485), and at least 2.8V 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.

ESD Protection
All pins on these devices include class 3 (>7kV) Human Body Model (HBM) ESD protection structures, but the RS-485 pins (driver outputs and receiver inputs) incorporate advanced structures allowing them to survive ESD events in excess of 16.5kV HBM and 16.5kV (1/2 duplex) IEC61000-4-2. The RS-485 pins are particularly vulnerable to ESD strikes 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. Twisted pair is the cable of choice for RS-485/422 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 20Mbps devices, to minimize reflections. Short networks using the 115kbps versions 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 bus) 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.
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-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 IEC61000 standard's 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. 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 ISL315XE 1/2 duplex 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. The result is a more repeatable and predictable test, but equipment limits prevent testing devices at voltages higher than 9kV. The RS-485 pins of all the ISL315XE versions survive 9kV contact discharges.
Built-In Driver Overload Protection
As stated previously, the RS-485 spec requires that drivers survive worst case bus contentions undamaged. These devices meet this requirement via driver output short circuit current limits, and on-chip thermal shutdown circuitry. The driver output stages incorporate short circuit current limiting circuitry which ensures that the output current never exceeds the RS-485 spec, even at the common mode voltage range extremes. 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 15 degrees. If the contention persists, the thermal shutdown/re-enable cycle repeats until the fault is cleared. Receivers stay operational during thermal shutdown.
Low Power Shutdown Mode
These CMOS transceivers all use a fraction of the power required by their bipolar counterparts, but they also include a shutdown feature that reduces the already low quiescent ICC to a 70nA 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. Note that receiver and driver enable times increase when the transceiver enables from shutdown. Refer to Notes 7, 8, 9, 10 and 11, at the end of the Electrical Specification table on page 8, for more information.
Data Rate, Cables, and Terminations
RS-485/422 are intended for network lengths up to 4000', but the maximum system data rate decreases as the transmission length increases. Devices operating at 20Mbps are limited to lengths less than 100', while the 115kbps versions can operate at full data rates with lengths of several thousand feet.
