The wide supply range from 3.15 V to 5.5 V lets it sit on a 3.3 V microcontroller UART without a separate level translator, or plug straight into a legacy 5 V backplane. Receiver hysteresis is 50 mV, which helps reject noise on long stub connections. No external level shifter, no separate transceiver supply — just one part number across both voltage domains. The 50 mV receiver hysteresis is a practical bonus: it cleans up slow edges on long cables without adding external Schmitt triggers. ## Package and temperature grade — rework and environment Surface-mount only; no through-hole option on this suffix. That means no end-of-life notice pending, no last-time-buy deadline to manage.","metaTitle":"SN65HVD1780DRG4 RS-485/RS-422 Transceiver, 115 kbps, 8-SOIC","metaDescription":"TI SN65HVD1780DRG4 half-duplex RS-485/RS-422 transceiver. 115 kbps data rate, 3.15 V to 5.5 V supply, 50 mV hysteresis, -40°C to 125°C.
