The ISO1432BDW from Texas Instruments is a high-performance, isolated RS-485 and RS-422 transceiver. It supports data rates up to 12 Mbps and offers full-duplex communication, making it suitable for demanding industrial applications.
This transceiver features robust EMC protection, including ±30kV HBM bus I/O protection, and high common-mode transient immunity (CMTI) of 100 kV/µs typical. It operates over an extended temperature range of -40°C to 125°C, ensuring reliability in harsh conditions. The device supports flexible supply voltages with VCC1 ranging from 1.71V to 5.5V and VCC2 from 3V to 5.5V.
Packaged in a 16-SOIC wide-body package, the ISO1432BDW is designed for surface mounting. It offers failsafe receiver functionality for bus open, short, and idle conditions, and supports up to 256 nodes on the bus with its 1/8 unit load capability. Safety certifications include compliance with DIN EN IEC 60747-17, UL 1577, and other relevant standards, providing high isolation ratings.
Key electrical specifications include a working isolation voltage of 1060 Vrms and a withstand isolation voltage of 5000 Vrms. The transceiver is compatible with TIA/EIA-485-A standards and PROFIBUS at a 5V bus-side supply. Its glitch-free power-up and power-down features are beneficial for hot-plugging scenarios.
