The 1 Mbps data rate is the maximum signaling speed. The 50 mV hysteresis in the receiver helps maintain margin on marginal cables. ## 5 V supply — not 3.3 V logic compatible The logic inputs (driver enable, data in) are 5 V-level thresholds. Direct connection to a 3.3 V UART without level translation will not reliably drive the logic inputs above the VIH minimum. Use a 3.3 V-to-5 V level shifter (e.g., a 74LVC1T45 or a simple resistor divider with a FET buffer) when interfacing a 3.3 V controller. The receiver output (RO) is a 5 V push-pull signal, so the receiving side must accept 5 V logic levels or buffer down to 3.3 V.","metaTitle":"SN65HVD52DR RS-485/422 Transceiver, 1 Mbps, Full Duplex","metaDescription":"Texas Instruments SN65HVD52DR RS-485/422 full-duplex transceiver, 1 Mbps data rate, 4.5-5.5V supply, 8-SOIC.
