ISL4485 Datasheet | Intersil

® ISL4485E Data Sheet December 2003 FN6049.1 ±15kV ESD Protected, 20Mbps, 5V, Low Power, RS-485/RS-422 Transceiver The Intersil ISL4485E is a high speed, BiCMOS 5V powered, single transceiver that meets both the RS-485 and RS-422 standards for balanced munication. Each driver output/receiver input is protected against ±15kV ESD strikes, without latch-up. Unlike petitive devices, this Intersil device is specified for 10% tolerance supplies (4.5V to 5.5V). The excellent differential output voltage coupled with high drive-current output stages allow 20Mbps operation over twisted pair networks up to 450 feet in length. The 25kΩ receiver input resistance presents a “single unit load” to...
