ISO1176 Datasheet Rs-485 Profibus Transceiver

Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community ISO1176 SLLS897E – MARCH 2008 – REVISED JUNE 2015 ISO1176 Isolated RS-485 Profibus Transceiver.

General 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 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.
