The Texas Instruments SN65HVD75DR is a single-transceiver RS-422 and RS-485 interface IC in an 8-pin SOIC package, combining one driver and one receiver for half-duplex operation. It supports data rates up to 20 Mbps, runs from a 3 V to 3.6 V supply (3.3 V nominal) drawing 950 uA, and provides 80 mV of receiver hysteresis for noise immunity. The device is specified from -40 C to +125 C and is RoHS compliant, lead free, and supplied on tape and reel.

RS-485 transceivers convert single-ended logic to the differential signalling used for long multi-drop cable runs in electrically noisy environments, making them the physical layer for Modbus RTU, PROFIBUS, DMX512, and many proprietary field buses. Half-duplex operation shares one twisted pair between transmit and receive under host direction control. Typical users include designers of factory automation and PLC I/O, building automation and HVAC controllers, motor drives, energy meters, and lighting control equipment. The +125 C rating and 3.3 V operation suit modern low-voltage industrial boards in warm cabinets.
