The ISO1176DW is a RS-485 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 2500VRMS of isolation per UL between the line transceiver and the logic level interface. The galvanically isolated differential bus transceiver is an integrated circuit designed for bidirectional data communication on multipoint bus-transmission lines. The transceiver combines a galvanically isolated differential line driver and differential input line receiver. The driver has an active-high enable with isolated enable-state output on the ISODE pin (pin 10) to facilitate direction control. The driver differential outputs and the receiver differential inputs connect internally to form a differential input/output (I/O) bus port.
