The 50 mV receiver hysteresis provides a clean noise margin on differential lines subject to ground shifts and coupled interference — a practical advantage over parts with 20 mV or unspecified hysteresis when the cable runs exceed 100 meters or passes near VFDs. The full-duplex architecture means separate transmit and receive pairs, so no direction-control GPIO is needed; the driver enable can be tied high permanently. ## 14-SOIC footprint and supply rail The 5V-only supply rail is a constraint — this part does not operate at 3.3V — so the design must carry a 5V bus or a local regulator. Decoupling with a 0.1 µF ceramic close to the supply pin is standard practice; the 50 mV hysteresis helps tolerate some supply ripple without false triggering. There is no NRND notice, last-time-buy window, or successor part number on file.","metaTitle":"SN65HVD54DR RS-485/RS-422 Transceiver, 5 Mbps, Full Duplex","metaDescription":"Texas Instruments SN65HVD54DR full-duplex RS-485/RS-422 transceiver in 14-SOIC. 5 Mbps data rate, 50 mV hysteresis, -40°C to 85°C.
