It handles one driver and one receiver, with 30 mV of receiver hysteresis to reject bus noise. At 50 Mbps this part runs RS-485 at the faster end of the standard, supporting high-speed data links like backplane communication or encoder feedback over short cable runs. The half-duplex architecture means you share the pair for transmit and receive, so the firmware needs to manage direction control via a GPIO or a dedicated DE signal. For slower fieldbus protocols (Profibus, Modbus at a few Mbps) the margin is generous. ## Supply range: 3V to 5.5V — one part for mixed-voltage boards The 3V to 5.5V supply range lets the THVD1450DR drop straight into a 3.3V microcontroller design without a level shifter, or sit on a legacy 5V industrial backplane. That single-supply flexibility simplifies the BOM and avoids the extra rail or translator IC. The receiver input common-mode range covers the RS-485 requirement of -7V to 12V, so it handles ground shifts on long cable runs.","metaTitle":"THVD1450DR RS-485 Transceiver, 50 Mbps, 8-SOIC","metaDescription":"Texas Instruments THVD1450DR half-duplex RS-485 transceiver. 50 Mbps data rate, 3V to 5.5V supply, -40°C to 125°C.
