The 30 mV receiver hysteresis cleans up slow edges on long twisted-pair runs, reducing the chance of chatter on an idle bus. If your design needs higher baud rates, you are looking at a different part family; for the 200 kbps tier, this is the part. ## 5 V rail and the retrofit angle If the board it is replacing or repairing runs on a 5 V rail — common in older PLC I/O modules, VFD control cards, and serial gateway boards — the SN65HVD3082ED fits without a voltage translation stage. The 8-SOIC footprint is a standard, widely supported land pattern that places cleanly on a two-layer board with basic decoupling.","metaTitle":"SN65HVD3082ED RS-485/RS-422 Transceiver, 200 kbps, 8-SOIC","metaDescription":"TI SN65HVD3082ED half-duplex RS-485/RS-422 transceiver, 200 kbps data rate, 4.5 V to 5.5 V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Half","Series":"-","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"200kbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"65HVD3082","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":"$1.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b1707cccdb891cd5db5ada9e0b0b115c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD3082ED/alternatives.json"},"ai":{"faq":[{"question":"Does SN65HVD3082ED support RS422?","answer":"Yes, the SN65HVD3082ED supports both RS-422 and RS-485 protocols in half-duplex mode.
