The 70 mV receiver hysteresis provides a clean noise margin on the differential inputs, and the full-duplex capability lets the bus carry simultaneous transmit and receive on separate wire pairs without a direction-control pin. At 400 kbps this transceiver handles the common RS-485 baud rates up to 38400 or 115200 with margin, but it is not intended for the multi-megabit PROFIBUS or DMX512 links that need 10 Mbps or higher. The 400 kbps ceiling suits applications where cable length runs tens to hundreds of metres — the slower edge rate reduces reflections and EMI compared to a higher-speed part on the same twisted pair. If your design needs a faster bus, the SN65HVD1471 family includes higher-rate variants (check the base product number 65HVD1471 for speed options); this specific DGK suffix locks in the 400 kbps grade.","metaTitle":"SN65HVD1471DGK RS-485/RS-422 Transceiver, Full Duplex","metaDescription":"TI SN65HVD1471DGK RS-485/RS-422 full-duplex transceiver, 400 kbps data rate, 3 V to 3.6 V supply, -40°C to 125°C, 8-VSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"400kbps","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD1471","Receiver Hysteresis":"70 mV","Operating Temperature":"-40°C~125°C","Supplier Device Package":"8-VSSOP","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5164","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1b77e1f02f3e6aa653cf272a9e3beb9b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1471DGK/alternatives.json"},"ai":{"faq":[{"question":"Is the SN65HVD1471DGK full duplex or half duplex?","answer":"It is a full-duplex transceiver, meaning the driver and receiver operate simultaneously on separate wire pairs without a direction-control signal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD1471DGK","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD1471DGK when reusing this data.
