It handles one driver and one receiver, supporting data rates up to 20 Mbps — fast enough for high-speed fieldbus links, motor drive encoder feedback, or multi-drop instrumentation networks running at extended cable lengths. The 70 mV of receiver hysteresis provides noise margin on long twisted-pair runs where ground potential differences and common-mode noise are present. ## Deployment temperature and supply rail The full-duplex capability eliminates the direction-control pin overhead of half-duplex parts, simplifying firmware for point-to-point links. Surface-mount only — no through-hole option. The narrow pitch means the PCB layout needs careful routing for the differential pair; keep the A and B traces matched and avoid stubs. The supply decoupling capacitor should sit within 2 mm of the VCC pin to keep the transceiver stable during fast edge transitions at 20 Mbps. This part qualifies for new production builds and ongoing BOM maintenance without an imminent replacement search.","metaTitle":"SN65HVD1474DGKR RS-485/RS-422 Transceiver, 20 Mbps, 8-VSSOP","metaDescription":"TI SN65HVD1474DGKR full-duplex RS-485/RS-422 transceiver, 20 Mbps data rate, 3V-3.6V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS422, RS485","Data Rate":"20Mbps","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD1474","Receiver Hysteresis":"70 mV","Operating Temperature":"-40°C~125°C","Supplier Device Package":"8-VSSOP","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6a3d6fbce07d753c614ee20fa6ce4e7a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1474DGKR/alternatives.json"},"ai":{"faq":[{"question":"Is the SN65HVD1474DGKR compatible with 3.3V logic?","answer":"Yes.
