Description

The IL485W has current limiting and thermal shutdown features to protect against output short circuits and bus contention situations where these may cause excessive power dissipation.

With a 1 nsec pulse skew and 16 nsec propagation delay, the IL485W is ideal for PROFIBUS applications. Use of DE/ISODE and IN1/OUT1 allows the IL485W to perform the handshaking operations of RTSAS and DTSAS of PROFIBUS.
