Each driver output and receiver input is protected against ±15kV ESD strikes without latch-up. Unlike competitive versions, these devices are specified for 10% tolerance supplies (4.5V to 5.5V).

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 that allows only one driver and up to 10 receivers on each bus, assuming one unit load devices. 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. An 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 4000ft, so the wide CMR is necessary to handle ground potential differences and voltages induced in the cable by external fields. Receiver Features These devices use a differential input receiver for maximum noise immunity and common-mode rejection. Input sensitivity is ±200mV as required by the RS-422 and RS-485 specifications. The receiver input resistance of 120kΩ surpasses the RS-422 specification of 4kΩ, and is more than eight times the RS-485 “UL” requirement of 12kΩ. Thus, these products are known as “one-eighth UL” transceivers. There can be up to 256 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 ±7V outside the power supplies (such as +12V and -7V), making them ideal for long networks in which induced voltages are a realistic concern. All the receivers include a “fail-safe if open” function that ensures a high level receiver output if the receiver inputs are unconnected (floating). Receivers easily meet the data rate supported by the corresponding driver, and the receiver outputs are tri-statable using the active low RE input. Driver Features The RS-485/422 driver is a differential output device that delivers at least 1.5V across a 54Ω load (RS-485) and at least 2V across a 100Ω load (RS-422). The drivers feature low propagation delay skew to maximize bit width and to minimize EMI. The driver outputs are tri-statable using the active high DE input. rate limited versions are a maximum of 250kbps. The ISL4491E driver outputs are not limited, so faster output transition times allow data rates of at least 15Mbps. Data Rate, Cables, and Terminations Twisted pair cable 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. RS-485/422 are intended for network lengths up to 4000ft, but the maximum system data rate decreases as the transmission length increases. Devices operating at 15Mbps are limited to lengths of a few hundred feet, while the 250kbps versions can operate at full data rates with lengths in excess of 1000ft. Proper termination is imperative to minimize reflections when using the 15Mbps devices. Short networks using the 250kbps versions do not need to 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, terminate the main cable in its characteristic impedance (typically 120Ω) at the end farthest from the driver. In multi-receiver applications, keep stubs connecting receivers to the main cable as short as possible. In multipoint (multi-driver) systems, terminate the main cable in its characteristic impedance at both ends. Keep stubs connecting a transceiver to the main cable as short as possible. Built-In Driver Overload Protection As stated previously, the RS-485 specification requires that drivers survive worst case bus contentions undamaged. The ISL44xxE devices meet this requirement through 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 specification, even at the common-mode voltage range extremes. Additionally, these devices use a foldback circuit that reduces the short-circuit current, and thus the power dissipation, when the contending voltage exceeds either supply. In the event of a major short-circuit condition, the ISL44xxE devices’ thermal shutdown feature disables the drivers when the die temperature becomes excessive. This eliminates the power dissipation, allowing the die to cool. The drivers automatically reenable after the die temperature drops about 15°C. If the contention persists, the thermal shutdown/reenable cycle repeats until the fault is cleared. Receivers stay operational during thermal shutdown. The ISL4489E driver outputs are slew rate limited to further reduce EMI and to minimize reflections in unterminated or improperly terminated networks. Data rates on these slew FN6074 Rev.4.00 Sep 17, 2018 Page 8 of 14 ISL4489E, ISL4491E ESD Protection All pins on these devices include Class 3 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 VCC = 5V, TA = 25°C; Unless Otherwise Specified 90 3.6 80 3.4 DIFFERENTIAL OUTPUT VOLTAGE (V) DRIVER OUTPUT CURRENT (mA) Typical Performance Curves 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 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 (for example, transient suppression diodes), and the associated undesirable capacitive load they present. 70 60 50 40 30 20 10 0 0 1 2 3 4 3.2 RDIFF = 100Ω 3 2.8 2.6 2.4 RDIFF = 54Ω 2.2 2 -40 5 -25 DIFFERENTIAL OUTPUT VOLTAGE (V) 50 25 75 FIGURE 6.
