This is faster than the common 250 kbps or 1 Mbps industrial RS-485 parts, but slower than 10-50 Mbps PROFIBUS or RS-422 variants. For a 115.2 kbps or 1 Mbps link, the 5 Mbps rating provides ample margin — the driver slew rate is not limited, so edge rates are fast; keep stub lengths under 6 inches to avoid reflections.","metaTitle":"SN65HVD51D RS-485/RS-422 Transceiver, 5 Mbps, Full Duplex","metaDescription":"Texas Instruments SN65HVD51D RS-485/RS-422 full-duplex transceiver. 5 Mbps data rate, 4.5V-5.5V supply, -40°C to 85°C.
