ISO15DWR Description

Short technical summary and product information.

The ISO15DWR from Texas Instruments is a robust isolated half-duplex differential line transceiver designed for RS-485 and RS-422 communication.

 

This device supports data rates up to 1 Mbps and provides a working isolation voltage of 400 Vrms, with a withstand isolation rating of 2500 Vrms per UL 1577 and CSA 62368-1. It features a common-mode transient immunity (CMTI) of 25 kV/µs and a typical transient immunity of 50 kV/µs, ensuring reliable operation in noisy environments.

 

The ISO15DWR operates from a 3.15V to 3.6V supply on both VCC1 and VCC2. It includes fail-safe receiver logic for idle, open, and short bus conditions. The transceiver is suitable for applications requiring robust, isolated serial communication.

 

Packaged in a 16-SOIC (0.295", 7.50mm Width) surface-mount package, the ISO15DWR is rated for an operating temperature range of -55°C to 125°C. It meets or exceeds TIA/EIA RS-485 requirements and supports up to 256 nodes on a bus with 1/8 unit load.
