Description
The IL485-3V is a galvanically isolated, high speed differential bus transceiver, designed for bidirectional data communication on balanced transmission lines. Isolation is achieved through patented* Isoloop® technology. The IL485-3V is the first isolated RS-485 interface available in a standard 16 pin SOIC package, which meets the ANSI Standards EIA/TIA-422-B and RS485 and is compatible with 3.3V input supplies.
The IL485-3V has current limiting and thermal shutdown features to protect against output short circuits and bus contention situations where these may cause excessive power dissipation.
With 1 nsec pulse skew and 16 nsec propagation delay, the IL485 is ideal for PROFIBUS applications.
