NVE IL 485-3V

The IL485 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 IL485 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. The IL485 has current limiting and thermal shutdown features to protect against output short circuits and bus contention situations that could cause excessive power dissipation. With 1 ns pulse skew and 16 ns propagation delay, the IL485 is ideal for PROFIBUS applications.
