That means TI has scheduled the end of production — the window to place final orders is closing. If this part is on your BOM, you need to secure lifetime buy quantities now or qualify a drop-in replacement before supply dries up. ## 3.3 V RS485 — the supply and signal story The RS485 bus pins are 5 V tolerant, so it can coexist on a bus with 5 V transceivers as long as the common-mode range is respected. The half-duplex architecture means a single twisted pair handles both transmit and receive, switched by the driver enable pin.","metaTitle":"SN65HVD11QDG4 RS485 Transceiver, 10 Mbps, 3.3 V, Last Buy","metaDescription":"TI SN65HVD11QDG4 half-duplex RS422/RS485 transceiver, 10 Mbps, 3V~3.6V supply, -40°C~125°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~125°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/SN65HVD11QDG4/alternatives.json"},"ai":{"faq":[{"question":"What is the direct replacement for SN65HVD11QDG4?","answer":"The evidence does not list an official TI replacement for this specific Q-grade variant.
