With a supply range of 3V to 3.6V, it runs cleanly on a 3.3V rail, which is the standard for many industrial microcontrollers and FPGAs. The 125°C upper limit covers the junction temperature under self-heating at full data rate; no derating is needed for most industrial enclosures. ## Full-duplex bus topology Full-duplex operation means the driver and receiver are active simultaneously on separate twisted pairs — the driver transmits on one pair while the receiver listens on another. This is the wiring scheme for point-to-point or multi-drop RS-422, and for four-wire RS-485 networks where a master talks on one pair and slaves reply on a second. If your backplane or cable harness already uses a half-duplex two-wire bus, you would need a different part; the SN65HVD1473D is built for the four-wire topology.","metaTitle":"SN65HVD1473D RS-485/RS-422 Transceiver, 20 Mbps, Full-Duplex","metaDescription":"TI SN65HVD1473D full-duplex RS-485/RS-422 transceiver, 20 Mbps data rate, 3V-3.6V supply, -40°C to 125°C, 14-SOIC.

The transceiver meets RS-485 electrical specs at that voltage, including the 1.5V differential output minimum under load. No level shifters are needed if your UART or MCU also runs at 3.3V."},{"question":"Does SN65HVD1473D support full-duplex communication?","answer":"Yes, it is a full-duplex transceiver with one driver and one receiver active simultaneously. That requires four wires — two for transmit, two for receive — typical of RS-422 or four-wire RS-485 networks."},{"question":"Can SN65HVD1473D be used as a direct replacement for SN65HVD1472D?","answer":"The SN65HVD1472D is a half-duplex variant (one driver, one receiver, but shared bus pins), while the SN65HVD1473D is full-duplex with separate driver and receiver pins. They are not pin-compatible for a drop-in swap — the bus wiring and PCB footprint differ. Check the base product number 65HVD1473 for the full-duplex family; the 1472 family is the half-duplex counterpart."},{"question":"Is SN65HVD1473D available in tape and reel packaging?","answer":"The listing shows a Tube package for this specific order code. TI also offers a tape-and-reel variant under a different suffix (typically SN65HVD1473DR). If your pick-and-place line needs reel packaging, order the 'R' suffix version."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD1473D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD1473D when reusing this data.
