The 30 mV of receiver hysteresis cleans up noisy bus signals without external filtering. ## Last-time-buy — plan your final order TI has placed the SN65HVD3085EDGK into Last Buy status. That means the manufacturer has announced end-of-life and is accepting final purchase orders within a defined window. Once that window closes, the part enters the surplus-and-broker channel exclusively. If you have an active BOM that calls out this exact order code, now is the time to secure your lifetime buy or qualify a drop-in replacement. ## What the 1 Mbps data rate and 5V supply mean for your design 1 Mbps is a solid mid-speed rating for RS-485 — fast enough for most industrial fieldbus applications (Modbus RTU, Profibus DP at lower speeds) without the signal-integrity headaches of multi-megabit links. The 5V supply (4.5V to 5.5V) is the classic industrial rail; it gives you good common-mode range and noise margin on long cable runs. If your system runs on 3.3V logic, you will need a level shifter or a 3.3V-rated transceiver variant. The half-duplex bus means a single twisted pair handles both transmit and receive — you manage direction with a GPIO pin on the driver enable. The SN65HVD3085EDGK comes in an 8-VSSOP package (also known as MSOP-8 or TSSOP-8, 0.118\" body width, 3.00 mm). It is a surface-mount part, so plan for a reflow profile. The small footprint saves board space but means the pin pitch is 0.65 mm — verify your PCB fab can handle that reliably. No exposed thermal pad on this package; keep the trace widths adequate for the bus current and route the differential pair with controlled impedance if the cable run is long.","metaTitle":"SN65HVD3085EDGK RS-485 Transceiver, 1 Mbps, 8-VSSOP","metaDescription":"TI SN65HVD3085EDGK half-duplex RS-422/RS-485 transceiver, 1 Mbps data rate, 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-TSSOP, 8-MSOP (0.118\\\", 3.00mm 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-VSSOP","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.1600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b1707cccdb891cd5db5ada9e0b0b115c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD3085EDGK/alternatives.json"},"ai":{"faq":[{"question":"Can the SN65HVD3085EDGK be used for RS-485 communication?","answer":"Yes.
