The 1 Mbps data rate covers most PLC, motor-drive, and building-automation links that run under 100 metres. Receiver hysteresis is 50 mV, which helps reject noise on long cable runs without external biasing. The 8-SOIC footprint is standard — layout matches any generic SOIC-8 RS-485 transceiver, so swapping in a different vendor's part (if pin-compatible) is a straight BOM edit.","metaTitle":"SN65HVD1786DR RS-485/RS-422 Transceiver, Half-Duplex, 1 Mbps","metaDescription":"TI SN65HVD1786DR half-duplex RS-485/RS-422 transceiver in 8-SOIC. 4.5V–5.5V supply, 1 Mbps data rate, 50 mV hysteresis, -40°C to 105°C.

The key difference is the data rate: the 1786 is rated for 1 Mbps, while the 1785 is a lower-speed variant.
