At 400 kbps the bit period is 2.5 µs. For a 100-metre RS-485 segment the propagation delay is roughly 550 ns one-way, leaving about 1.4 µs of timing margin per bit after accounting for driver and receiver delays. This is adequate for polled Modbus or ASCII protocols but too slow for high-throughput Profibus or CAN-based motion networks. It can be specified into a production BOM without near-term obsolescence concern. ## Package and footprint — 8-VSSOP The tube delivery is typical for prototype and low-volume builds; reel quantities are available through the supply chain.","metaTitle":"SN65HVD71DGK RS-485 Transceiver, 400 kbps, Full Duplex","metaDescription":"TI SN65HVD71DGK RS-422/RS-485 full-duplex transceiver, 400 kbps data rate, 3 V to 3.6 V supply, -40°C to 125°C range, 8-VSSOP package.","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":"65HVD71","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":"$3.6379","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9087c32540c5c64471c20d05147d7cee.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD71DGK/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN65HVD71DGK and SN65HVD72DGK?","answer":"The SN65HVD72DGK is a pin-compatible sibling in the same family. The primary difference is data rate: the SN65HVD72DGK supports 1 Mbps versus the 400 kbps of the SN65HVD71DGK. Both share the same 8-VSSOP footprint, supply range, and temperature grade, so a board designed for the 71 can accept the 72 for a speed upgrade without layout changes."},{"question":"What is the data rate of SN65HVD71DGK?","answer":"The data rate is 400 kbps, full duplex."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD71DGK","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD71DGK when reusing this data.
