The Texas Instruments ISO1430DWR is a robust, EMC-protected, isolated RS-485 and RS-422 transceiver designed for reliable communication in harsh environments. It supports half-duplex operation with a maximum data rate of 12Mbps.
Key electrical specifications include a working isolation voltage of 1060 Vrms, surge isolation voltage up to 10000 VPK, and transient isolation voltage of 7071 VPK. The device offers 5000 Vrms isolation for one minute per UL 1577. It features a wide operating voltage range from 1.71V to 5.5V for the logic side (VCC1) and 3V to 5.5V for the bus side (VCC2).
Designed for demanding applications, the ISO1430DWR provides ±30kV HBM, ±16kV IEC 61000-4-2 contact, and ±4kV IEC 61000-4-4 electrical fast transient protection. It includes failsafe receiver logic for bus open, short, and idle conditions, and supports up to 256 nodes on the bus with 1/8 unit load. The transceiver operates reliably within an extended temperature range of -40°C to 125°C.
Packaged in a 16-pin wide-body SOIC package, the ISO1430DWR is suitable for surface mounting. Its design ensures glitch-free power-up and power-down for hot-plugging applications and offers pin compatibility with many existing isolated RS-485 transceivers.
