The SN65HVD1792DR is full duplex, meaning it uses two separate twisted pairs — one for transmit, one for receive — so the bus can send and receive simultaneously without toggling the driver enable. That matters if you are replacing an RS-422 link or building a point-to-point connection where latency matters and you do not want to manage direction in firmware. The trade-off: you need two pairs instead of one, but the wiring is simpler and the protocol overhead drops. It is a current-production part available through independent distribution. ## Package and footprint: 14-SOIC The footprint is standard for this body size — no odd pad pitch or exposed pad to route. The tape-and-reel and cut-tape options cover both prototyping and volume reflow.","metaTitle":"SN65HVD1792DR RS-485/RS-422 Transceiver, Full Duplex, 1 Mbps","metaDescription":"TI SN65HVD1792DR is a full-duplex RS-485/RS-422 transceiver in 14-SOIC, 1 Mbps data rate, 4.5V-5.5V supply, -40°C to 105°C.
