15kV ESD Protected, 3.3V, Full Fail-safe, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers
The Intersil ISL8307XE are BiCMOS 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. These devices have very low bus currents (+125A/-100A), 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. For example, in a remote utility meter reading system, individual meter readings are routed to a concentrator via an RS-485 network, so the high allowed node count minimizes the number of repeaters required. Receiver (Rx) inputs feature a "Full Fail-Safe" design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or terminated but undriven. Hot Plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state while the power supply stabilizes. The ISL83070E through ISL83075E utilize slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications. Slew rate limited versions also include receiver input filtering to enhance noise immunity in the presence of slow input signals. The ISL83070E, ISL83071E, ISL83073E, ISL83076E, ISL83077E are configured for full duplex (separate Rx input and Tx output pins) applications. The half duplex versions multiplex the Rx inputs and Tx outputs to allow transceivers with output disable functions in 8 lead packages.

4. 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. When testing devices with the shutdown feature, keep RE = 0 to prevent the device from entering SHDN. 8. When testing devices with the shutdown feature, the RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN. 9. Versions with a shutdown feature are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, 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.

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 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.
Receiver 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 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. Receiver inputs function with common mode voltages as great as +9V/-7V outside the power supplies (i.e., +12V and -7V), making them ideal for long networks where induced voltages, and ground potential differences, are realistic concerns. All the receivers include a "full fail-safe" function that guarantees a high level receiver output if the receiver inputs are unconnected (floating) or shorted. Fail-safe with shorted inputs is achieved by setting the Rx upper switching point to -50mV, thereby ensuring that the Rx sees 0V differential as a high input level.

ISL83070E, ISL83071E, ISL83072E, ISL83073E, ISL83075E, ISL83076E, ISL83077E, ISL83078E
Receivers easily meet the data rates supported by the corresponding driver, and all receiver outputs - except on the ISL83071E and ISL83077E- are tri-statable via the active low RE input. versions can operate at full data rates with lengths of several thousand feet. 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 250kbps 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.
Driver Features
The RS-485/422 driver is a differential output device that delivers at least 1.5V across a 54 load (RS-485), and at least 2V across a 100 load (RS-422). The drivers feature low propagation delay skew to maximize bit width, and to minimize EMI. All drivers are tri-statable via the active high DE input, except on the ISL83071E and ISL83077E. The 250kbps and 500kbps driver outputs are slew rate limited to minimize EMI, and to reduce reflections in unterminated or improperly terminated networks. Outputs of the ISL83076E - ISL83078E drivers are not limited, so faster output transition times allow data rates of at least 20Mbps.
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 ISL8307XE family incorporates a "Hot Plug" function. During power up, circuitry monitoring VCC ensures that the Tx and Rx outputs remain disabled for a period of time, regardless of the state of DE and RE. This gives the processor/ASIC a chance to stabilize and drive the RS-485 control lines to the proper states.
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. Additionally, these devices utilize a foldback circuit which reduces the short circuit current, and thus the power dissipation, whenever the contending voltage exceeds either supply. 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.
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 15kV HBM. 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, protect without allowing any latchup mechanism to activate, 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.
Low Power Shutdown Mode
These CMOS transceivers all use a fraction of the power required by their bipolar counterparts, but some also include a shutdown feature that reduces the already low quiescent ICC to a 10nA 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 50ns 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 7-11, at the end of the Electrical Specification table, 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 250kbps
