ISO1176 隔离 PROFIBUS RS-485 收发器

The ISO1176 is an isolated differential line transceiver designed for use in PROFIBUS applications. The device is ideal for long transmission lines since 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 between the line transceiver and the logic level interface.

The galvanically isolated differential bus transceiver is an integrated circuit designed for bi-directional 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.
