Half-duplex operation means the driver and receiver share the same bus wires; the driver enable pin (DE) must be toggled by the host UART or GPIO to switch direction. The 50 mV of receiver hysteresis provides clean switching on long cables where signal edges may be degraded by reflections or DC offsets. ## Supply voltage and 5V system compatibility It can be used directly with 5 V microcontrollers without level shifting on the logic interface. For 3.3 V systems, the logic inputs are not 3.3 V-tolerant at the full supply range — a level translator or a 3.3 V-rated RS485 part would be the correct choice. Housed in an 8-pin SOIC package (body 3.90 mm wide), the SN65HVD1787DR is a drop-in replacement for many industry-standard half-duplex RS485 transceivers in the same footprint.","metaTitle":"SN65HVD1787DR RS485 Transceiver, 10 Mbps, Half-Duplex","metaDescription":"Texas Instruments SN65HVD1787DR half-duplex RS422/RS485 transceiver. 10 Mbps data rate, 4.5V-5.5V supply, -40°C to 105°C.
