The 35 mV receiver hysteresis helps reject noise on long cable runs typical of factory-floor Modbus or BACnet links. ## Supply voltage flexibility — one part for 3.3V and 5V buses A 3.3V-only RS-485 transceiver locks you into a voltage domain; this part works across both, so a BOM that spans 3.3V MCUs and 5V legacy peripherals can use the same transceiver. No extra regulator or level translator needed on the supply side. The half-duplex architecture with one driver and one receiver is the standard for two-wire RS-485 buses where direction is toggled by a microcontroller GPIO. For a storeroom or BOM planner, that means no last-time-buy scramble in the next few years. Store the reels dry — the SOIC-8 package is MSL 1 or 3 depending on date code, but standard handling applies.","metaTitle":"SN65HVD08D RS-422/RS-485 Transceiver, 3V-5.5V, Half-Duplex","metaDescription":"Texas Instruments SN65HVD08D half-duplex RS-422/RS-485 transceiver in SOIC-8. 3V to 5.5V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Half","Series":"-","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"-","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Base Product Number":"65HVD08","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":"$6.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8524f6f64bae11d3908836b3d999f04c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD08D/alternatives.json"},"ai":{"faq":[{"question":"Does SN65HVD08D operate at 3.3V supply?","answer":"Yes. The SN65HVD08D supply range is 3V to 5.5V, so it operates at 3.3V without issue. The receiver hysteresis and driver output levels are specified across that range."},{"question":"What is the closest pin-compatible alternative to SN65HVD08D in this component family?","answer":"Within the 65HVD08 family, the SN65HVD08D is the SOIC-8, -40°C to 85°C variant. The SN65HVD08DR (same die, tape-and-reel packaging) is pin-compatible. For a wider temperature range, the SN65HVD087D (same footprint, -40°C to 125°C) is a drop-in if the application needs extended temperature."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD08D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD08D when reusing this data.
