The single driver/receiver pair (1/1) suits point-to-point or multi-drop with one talker at a time. ## 80 mV hysteresis — noise margin on long cable runs Receiver hysteresis is specified at 80 mV, which filters reflections and common-mode noise on cables that run tens of metres through a factory floor. Without that margin a 50 Mbps link would false-trigger on every stub reflection. TI lists the SN65HVD78DRBT as Active. That means no last-time-buy window to chase, no risk of a forced redesign mid-production.","metaTitle":"SN65HVD78DRBT RS-485 Transceiver, 50 Mbps, 3.3V","metaDescription":"TI SN65HVD78DRBT half-duplex RS-485 transceiver, 50 Mbps data rate, 3V-3.6V supply, 80 mV hysteresis, -40°C to 125°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":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS422, RS485","Data Rate":"50Mbps","Mounting Type":"Surface Mount","Package / Case":"8-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD78","Receiver Hysteresis":"80 mV","Operating Temperature":"-40°C~125°C","Supplier Device Package":"8-SON (3x3)","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/01d3b90c85b255b169123cd5f5519c00.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD78DRBT/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN65HVD78DRBT and SN65HVD78D?","answer":"The SN65HVD78DRBT uses an 8-VDFN exposed pad package (3x3 mm), while the SN65HVD78D is in an 8-SOIC.
