ISO1176 Description
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 mon-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.
