ISO1176TDW Description

Short technical summary and product information.

The ISO1176TDW from Texas Instruments is a high-performance isolated differential line transceiver designed for RS-485 and RS-422 communication. It features an integrated transformer driver, simplifying isolated power design and enabling efficient operation with signaling rates up to 40 Mbps. This device breaks ground loops, allowing operation with a larger common-mode voltage range, making it ideal for long transmission lines.

 

Key electrical specifications include a working isolation voltage of 400 Vrms, a surge isolation voltage of 4000 VPK, and a transient isolation voltage of 4242 VPK. It boasts a minimum common-mode transient immunity of 25 kV/µs and a typical transient immunity of 50 kV/µs. The transceiver operates across a temperature range of -40°C to 85°C and supports a data rate of up to 40 Mbps.

 

Compliance and safety standards are met, including basic insulation per DIN EN IEC 60747-17 (VDE 0884-17) and 2500 Vrms isolation for 1 minute per UL 1577 and CSA standards. The ISO1176TDW is supplied in a 16-SOIC package and is designed for surface mount applications. It meets or exceeds the requirements of EN 50170 and TIA/EIA-485-A.
