IL422-3V General Description


The IL422-3V is a galvanically isolated, high speed differential driver and receiver pair, designed for bidirectional data communication on balanced transmission lines. Isolation is achieved through patented* Isoloop® technology. The IL422-3V is the first isolated RS-422 interface available in a standard 16 pin SOIC package, which meets the ANSI Standards EIA/TIA-422-B and RS485.

The IL422-3V has current limiting and thermal shutdown features to protect against output short circuits and bus contention situations where these may cause excessive power dissipation.
