The full-duplex architecture eliminates the need for direction control, simplifying the firmware and reducing the pin count on the UART side. The 50 mV hysteresis cleans up the received signal on a loaded bus, reducing bit-error rate in noisy factory environments. The 14-SOIC body (3.90 mm width) is a common footprint that fits existing PCB layouts for RS-485 nodes. Surface-mount assembly keeps the board single-sided compatible for low-cost designs.","metaTitle":"SN65HVD54DG4 RS-422/RS-485 Transceiver, 5 Mbps, Full Duplex","metaDescription":"TI SN65HVD54DG4 full-duplex RS-422/RS-485 transceiver in 14-SOIC. 5 Mbps data rate, 4.5 V to 5.5 V supply, -40°C to 85°C.
