At 50Mbps, this transceiver supports high-speed RS-485 links for encoder feedback, motion-control networks, or backplane communication. The full-duplex architecture lets data flow in both directions simultaneously, doubling throughput on a four-wire bus compared to half-duplex designs that must arbitrate direction. The 70 mV of receiver hysteresis helps reject noise on long cable runs without external filtering. ## 3.3V supply rail and temperature range Surface-mount assembly in the 8-VSSOP footprint keeps board area small. For dual-sourcing assurance, the SN65HVD77D is a pin-compatible sibling in a different package (8-SOIC) — same electrical specification, same data rate, same supply range.","metaTitle":"SN65HVD77DGK RS-485/RS-422 Transceiver, 50Mbps, 3V-3.6V","metaDescription":"TI SN65HVD77DGK full-duplex RS-485/RS-422 transceiver, 50Mbps data rate, 3V-3.6V supply, -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":"Full","Series":"-","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"50Mbps","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":"65HVD77","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":"$4.3035","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/951f0576f7dcacc741975e18e12f400c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD77DGK/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of SN65HVD77DGK?","answer":"The SN65HVD77DGK supports a data rate of 50Mbps."},{"question":"What is the difference between SN65HVD77DGK and SN65HVD77D?","answer":"The SN65HVD77DGK is in an 8-VSSOP package, while the SN65HVD77D is in an 8-SOIC package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD77DGK","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD77DGK when reusing this data.
