At 50 Mbps, this transceiver supports back-to-back data frames without the bus-turnaround dead cycles that half-duplex RS-485 imposes. Full-duplex operation uses a second twisted pair for the transmit path, so the driver and receiver are active simultaneously — useful for real-time control loops where the controller sends a command and reads the response without waiting for the bus to release. The 70 mV hysteresis on the receiver input rejects noise picked up on long cable runs, reducing bit errors in electrically noisy environments. That means no last-time-buy notice looming, no end-of-life clock ticking. The base product number 65HVD1477 covers the family; this specific variant is the DGKR suffix in the 8-VSSOP package. ## 3.3V-only rail — plan the supply accordingly This part is not 5V-tolerant on the bus pins or the logic interface. Surface-mount only.","metaTitle":"SN65HVD1477DGKR RS-485/RS-422 Transceiver, 50 Mbps, 8-VSSOP","metaDescription":"Texas Instruments SN65HVD1477DGKR full-duplex RS-485/RS-422 transceiver. 50 Mbps data rate, 3V-3.6V supply, -40°C to 125°C.
