If your design uses a 3.3V supply for the UART side, you will need level translation or a different transceiver rated for the lower voltage. The half-duplex architecture means the driver and receiver share the same bus pins, with the driver enable controlling direction — typical for two-wire RS-485 networks where the host toggles DE between transmit and receive. TI lists the SN65HVD3085ED with a Last Buy lifecycle status. That means the manufacturer has announced end-of-life and is accepting final orders for a limited window. Once that window closes, the only channel will be independent distribution handling new-old-stock and surplus. For a production BOM that depends on this transceiver, the prudent move is to qualify a replacement or secure a lifetime buy quantity now.","metaTitle":"TI SN65HVD3085ED RS-485/RS-422 Transceiver, Half-Duplex","metaDescription":"SN65HVD3085ED from Texas Instruments: half-duplex RS-485/RS-422 transceiver, 1Mbps data rate, 4.5V-5.5V 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":"1Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Last Time Buy","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"65HVD3085","Receiver Hysteresis":"30 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b1707cccdb891cd5db5ada9e0b0b115c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD3085ED/alternatives.json"},"ai":{"faq":[{"question":"What is the recommended replacement for SN65HVD3085ED?","answer":"For a pin-compatible alternative within the same TI 65HVD308x family, the SN65HVD3082ED shares the same 8-SOIC footprint and half-duplex RS-485 function, but check its data rate and supply specs against your bus timing budget before substituting."},{"question":"Can SN65HVD3085ED be used with a 3.3V supply?","answer":"No — the supply range is 4.5V to 5.5V, so this transceiver requires a 5V rail.
