Rate Limited, Full Duplex, RS-485/RS-422 Transceivers FN6074 Rev.4.00 Sep 17, 2018 The ISL4489E and ISL4491E are ESD protected, “fractional” Unit Load (UL), BiCMOS, 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 ±15kV ESD strikes without latch-up. Unlike competitive versions, these devices are specified for 10% tolerance supplies (4.5V to 5.5V). The Rx inputs and Tx outputs present a 1/8 unit load to the RS-485 bus, which allows a total of 256 transmitters and receivers on the network for large node count
