ISO1176DWR Description

Short technical summary and product information.

The ISO1176DWR from Texas Instruments is a robust isolated differential line transceiver ideal for PROFIBUS applications and long transmission lines. It breaks the ground loop, enabling operation with a larger common-mode voltage range.

 

This device supports signaling rates up to 40 Mbps and features a typical transient immunity of 50 kV/µs. It includes fail-safe receiver logic for bus open, short, or idle conditions and offers 3.3 V inputs that are 5 V tolerant. The transceiver provides 16 kV HBM ESD protection between bus pins and GND2, and 6 kV HBM between bus pins and GND1.

 

With a 2500 Vrms isolation rating per UL 1577 and 4000 V PK isolation per CSA 62368-1, the ISO1176DWR ensures reliable operation in demanding environments. It is designed for bidirectional data communication on multipoint buses and can accommodate up to 160 transceivers on a single bus.

 

The ISO1176DWR is available in a 16-SOIC surface mount package, operating within a temperature range of -40°C to 85°C. It is supplied on large tape and reel for automated assembly.
