On a 1000-meter RS-485 run at 1 Mbps, ground-potential differences and reflections can push the received signal into the noise band; the hysteresis buys you enough deadband to keep the UART from seeing false start bits. For comparison, older SN75176-type parts have no specified hysteresis and rely entirely on external termination and biasing to achieve the same noise immunity. The base product number 65HVD12 covers a family of speed and package variants, so if a future spin needs a different data rate or a smaller footprint, the migration stays within the same TI process node.","metaTitle":"SN65HVD12DR RS-485/RS-422 Transceiver, 1 Mbps, 8-SOIC","metaDescription":"TI SN65HVD12DR half-duplex RS-485/RS-422 transceiver, 1 Mbps data rate, 3 V to 3.6 V supply, 35 mV hysteresis, -40°C to 85°C, 8-SOIC.","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":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS422, RS485","Data Rate":"1Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD12","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":"$4.0600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8184a8761e2cd96372c20ad22682ea16.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD12DR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN65HVD12DR and SN65HVD12D?","answer":"The SN65HVD12DR is the tape-and-reel packaged variant of the SN65HVD12D, which ships in tubes. The DR suffix indicates reel packaging for automated pick-and-place assembly; the D suffix is for tube shipments.
