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

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.

Driver output enable.

® 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
