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 V RMS 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 that is designed to offer minimum loading to the bus allowing up to 160 nodes.

The PV pin (pin 7) is provided as a full-chip enable option. All device outputs become high impedance when a logic low is applied to the PV pin. For more information, see the function tables in .

Any cabled I/O can be subjected to electrical noise transients from various sources. These noise transients can cause damage to the transceiver and/or nearby sensitive circuitry if they are of sufficient magnitude and duration. The ISO1176 can significantly reduce the risk of data corruption and damage to expensive control circuits.

The device is characterized for operation over the ambient temperature range of –40°C to +85°C.
