At this rate, cable length is limited by the driver's slew rate and the bus capacitance — expect reliable operation up to a few hundred meters with proper termination. For applications needing faster throughput, a sibling with a higher data rate (e.g., 20 Mbps or 50 Mbps) would be the alternative, but the 1 Mbps variant keeps EMI lower and simplifies layout. ## Last Buy — the sourcing window is closing The SN65HVD3085EDG4 carries a Last Buy product status per the manufacturer's lifecycle record. For a BOM line already qualified to this exact order code, the priority is to secure inventory before the window closes.","metaTitle":"SN65HVD3085EDG4 Transceiver, RS-422/RS-485, 1 Mbps, 8-SOIC","metaDescription":"TI SN65HVD3085EDG4 half-duplex RS-422/RS-485 transceiver, 1 Mbps data rate, 4.5V-5.5V supply, -40°C to 85°C.","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":"$3.1067","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b1707cccdb891cd5db5ada9e0b0b115c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD3085EDG4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for SN65HVD3085EDG4?","answer":"The base product number 65HVD3085 covers multiple suffix variants; a pin-compatible, active-status sibling in the same family may serve as a substitute, but verify the full order code, supply voltage, and temperature grade match your design before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD3085EDG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD3085EDG4 when reusing this data.
