ISO1450BDWR Description

Short technical summary and product information.

The Texas Instruments ISO1450BDWR is a galvanically-isolated differential line transceiver designed for TIA/EIA RS-485 and RS-422 applications. It is built to withstand harsh industrial environments, featuring robust EMC protection including ±30kV HBM and ±16kV IEC 61000-4-2 contact discharge protection.

 

This transceiver supports data rates of up to 50 Mbps and operates with a logic-side supply voltage from 1.71V to 5.5V and a bus-side supply from 3V to 5.5V. It provides 5000 VRMS isolation for 1 minute per UL 1577 and meets various safety certifications including DIN EN IEC 60747-17, GB 4943.1, IEC 62368-1, IEC 60601-1, and IEC 61010-1.

 

The ISO1450BDWR is housed in a 16-SOIC wide-body package, suitable for surface mounting. It features a failsafe receiver for bus open, short, and idle conditions, and offers 1/8 unit load for up to 256 nodes on the bus. The device also boasts high common-mode transient immunity (100 kV/µs typical) and glitch-free power-up and power-down for hot-plugging applications.

 

With an extended operating temperature range of -40°C to 125°C, this isolated transceiver is ideal for demanding industrial communication systems requiring reliable and noise-immune data transmission.
