ISO15DW Description

Short technical summary and product information.

The Texas Instruments ISO15DW is a half-duplex, isolated differential line transceiver designed for TIA/EIA-485/422 applications. It supports signaling rates up to 1 Mbps and provides robust isolation with a working isolation voltage of 400Vrms and a withstand isolation voltage of 2500Vrms.

 

Key electrical specifications include a data rate of 1 Mbps, a common mode transient immunity of 25 kV/µs, and a low bus capacitance of 16 pF typical. The device operates with supply voltages between 3.15V and 3.6V for both VCC1 and VCC2. It features a fail-safe receiver for bus open, short, and idle conditions, and its 3.3V inputs are 5V tolerant.

 

This transceiver meets or exceeds TIA/EIA RS-485 requirements and supports up to 256 nodes on a bus with 1/8 unit load. It includes thermal shutdown protection. The operating temperature range is -40°C to 125°C.

 

The ISO15DW is available in a 16-SOIC package and is designed for surface mount applications. It has achieved safety and regulatory approvals including 4000-V PK V IOTM, 560-V PK V IORM per DIN EN IEC 60747-17, 2500 V RMS isolation per UL 1577, and 2500 V RMS isolation per CSA 62368-1.
