DESCRIPTION of ISO1176DWR

The ISO1176 device is an isolated differential line transceiver designed for use in PROFIBUS
applications. The device is ideal for long transmission lines because the ground loop is broken to provide for
operation with a much larger common-mode voltage range. The symmetrical isolation barrier of each
device is tested to provide 2500 VRMS of isolation per UL between the line transceiver and the logic level interface
