The IL422E isolated RS-485/RS422 interface from NVE is an industry-standard differential bus transciever, designed to galvanically isolate bidirectional data communication over balanced transmission lines. The IL422 series is also compatible with 3V and 5V input supplies. The device uses NVE’s patented IsoLoop spintronic Giant
Magnetoresistance (GMR) technology and comes in a 0.3″ 16-pin SOIC
IL422 was the first isolated RS-422 transciever in a standard 16-pin SOIC package to meed the ANSI Standards EIA/TIA-422-B and RS-485.
