The Texas Instruments SN65HVD30DR is a full-duplex RS-422/RS-485 transceiver in an 8-SOIC package, designed for point-to-point or multidrop differential data links where the bus must sustain 26 Mbps without dead cycles from direction toggling. Full-duplex operation means separate driver and receiver pairs are active simultaneously, so the part suits applications like motor-drive encoder feedback, VFD communication, or PLC backplanes where the host sends commands while reading status on the same twisted pair set.
Industrial temperature and supply — fit for factory-floor networks
If your existing BOM runs 5 V RS-485 transceivers, this part needs a supply change or level translation on the logic side.
