The full-duplex capability means separate transmit and receive paths, so you don't waste bus cycles turning the driver around; the 1/1 driver/receiver count is exactly what a point-to-point link needs. ## 125°C junction — industrial and motor-drive environments The 70 mV receiver hysteresis cleans up noise on long cable runs — a common pain point in factory-floor RS-485 installations where ground potential differences and coupled motor noise eat signal margin. TI lists the SN65HVD1477DR as Active. That means no last-time-buy deadline, no end-of-life notice on the horizon. The base product number is 65HVD1477, so any future PCNs or die revisions will track under that root.","metaTitle":"SN65HVD1477DR RS-485/RS-422 Transceiver, 50 Mbps","metaDescription":"TI SN65HVD1477DR is a 50 Mbps full-duplex RS-485/RS-422 transceiver in 8-SOIC. 3V–3.6V supply, -40°C to 125°C.

That is the maximum specified under the RS-422/RS-485 protocol — enough for high-speed point-to-point links or multi-drop networks running at lower rates."},{"question":"Is SN65HVD1477DR full duplex?","answer":"Yes, the SN65HVD1477DR is a full-duplex transceiver. It has separate driver and receiver paths, so you can transmit and receive simultaneously on a four-wire RS-422 bus or a two-pair RS-485 network."},{"question":"What is the difference between SN65HVD1477DR and SN65HVD1476DR?","answer":"The SN65HVD1477DR is a full-duplex transceiver, while the SN65HVD1476DR is half-duplex.
