The 50 mV hysteresis cleans up slow edges on unterminated stubs — helpful in noisy factory-floor drops where the common-mode voltage swings. Full-duplex operation means separate pairs for TX and RX, so you need two twisted pairs in the cable, not one. The 14-SOIC footprint is a standard body width (3.90 mm) and matches the SN65HVD1791DR pinout — a direct drop-in for that base number. ## Active lifecycle — safe for new BOMs For a procurement desk qualifying a new 5 V RS-485 interface, this part carries no imminent obsolescence risk.","metaTitle":"SN65HVD1791DRG4 RS-485/RS-422 Full-Duplex Transceiver","metaDescription":"Texas Instruments SN65HVD1791DRG4 RS-485/RS-422 full-duplex transceiver, 115 Kbps data rate, 4.5 V to 5.5 V supply, -40°C to 105°C.
