This part is officially in Last Buy status. That means TI has issued a last-time-buy window, after which no further factory orders will be accepted. If this transceiver is on your active BOM, the decision is immediate: place a lifetime buy to cover remaining production, or qualify a pin-compatible replacement before the LTB closes. The 8-SOIC footprint is shared across many RS-485 transceivers, so a swap is feasible — but the qualification work needs to start now, not when stock runs dry. ## Supply rail and bus margin At 10 Mbps, the half-duplex bus needs proper termination (typically 120 Ω at each end) and stub lengths kept short to avoid reflections. The 35 mV hysteresis helps reject common-mode noise on the differential pair, which matters when the cable runs through a noisy industrial environment.","metaTitle":"SN65HVD11DG4 RS-485/RS-422 Transceiver, 10 Mbps, Half-Duplex","metaDescription":"Texas Instruments SN65HVD11DG4 half-duplex RS-485/RS-422 transceiver, 10 Mbps data rate, 3 V to 3.6 V supply, -40°C to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Half","Series":"-","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"10Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Last Time Buy","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD11","Receiver Hysteresis":"35 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0369","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8184a8761e2cd96372c20ad22682ea16.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD11DG4/alternatives.json"},"ai":{"faq":[{"question":"Is SN65HVD11DG4 obsolete?","answer":"It is in Last Buy status — the last-time-buy window is open, but once it closes, TI will no longer manufacture it.
