ISL4485 - 15kV ESD Protected/ 20Mbps/ 5V/ Low Power/ RS-485/RS-422 Transceiver

Description

PIN RO RE DE DI GND A/Y FUNCTION Receiver output: If A > B by at least 0.2V, RO is high; If A < B by 0.2V or more, RO is low; RO = High if A and B are unconnected (floating).

Receiver output enable.

RO is enabled when RE is low; RO is high impedance when RE is high.

® 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 communication. Each driver output/receiver input is protected against ±15kV ESD strikes, without latch-up. Unlike competitive 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 the RS-485 bus, allowing up to 32 transceivers on the network.
