Description

The IL485W is a galvanically isolated, high-speed differential bus transceiver, designed for bidirectional data communication on balanced transmission lines. The devices use NVE’s patented* IsoLoop spintronic Giant Magnetoresistance (GMR) technology. The IL485W is the first isolated RS-485 interface in a standard 16-pin SOIC package that meets the ANSI Standards EIA/TIA-422-B and RS-485 and is compatible with 3.3V input supplies.
