ISO1452DWR Description

Short technical summary and product information.

The ISO1452DWR from Texas Instruments is a high-performance, galvanically-isolated differential line transceiver suitable for TIA/EIA RS-485 and RS-422 applications. Operating at data rates up to 50 Mbps, this transceiver provides full-duplex communication and is designed to withstand demanding industrial conditions.

 

Key electrical features include a wide operating voltage range for both logic-side (1.71V to 5.5V) and bus-side (3V to 5.5V) supplies. It boasts robust Bus I/O protection, including ±30kV HBM and ±16kV IEC 61000-4-2 contact discharge protection, along with 100kV/µs typical common-mode transient immunity. The device also offers failsafe receiver operation for bus open, short, and idle conditions, supporting up to 256 nodes on the bus with 1/8 unit load.

 

Packaged in a 16-SOIC wide-body format, the ISO1452DWR is designed for surface mounting. It operates across an extended temperature range of -40°C to 125°C, making it suitable for challenging environments. The transceiver meets stringent safety standards, including 5000 VRMS isolation per UL 1577 and certifications for various international safety standards, ensuring reliable operation in critical applications.
