A single driver and single receiver pair handles the differential bus, and the 30 mV receiver hysteresis cleans up noise on long cable runs where ground offset and reflections eat into the signal margin. ## Temperature grade and supply flexibility The 3V to 5.5V supply tolerance is wide enough that a 3.3V rail with 5% regulation still keeps the transceiver in spec; at the 5V end it matches legacy 5V-only bus nodes without level translation.","metaTitle":"TI THVD1450DGK RS-485 Transceiver, 50 Mbps, Half-Duplex","metaDescription":"Texas Instruments THVD1450DGK half-duplex RS-485 transceiver, 50 Mbps data rate, 3V to 5.5V 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":"Half","Series":"-","Package":"Tube","Protocol":"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 ~ 5.5V","Base Product Number":"THVD1450","Receiver Hysteresis":"30 mV","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"8-VSSOP","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/57d82a1f3a185d1c0139eeb9c1b361a6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/THVD1450DGK/alternatives.json"},"ai":{"faq":[{"question":"Is THVD1450DGK compatible with 3.3V supply?","answer":"Yes. The supply range covers 3V to 5.5V, so the THVD1450DGK operates directly from a 3.3V rail without a separate regulator. At 3.3V the driver output swing still meets the RS-485 differential output spec for bus lengths up to several hundred meters at lower data rates."},{"question":"What is the best replacement or equivalent for THVD1450DGK?","answer":"Within the THVD1450 family, the base product number covers multiple speed and package variants. For a pin-compatible alternative at the same 50 Mbps speed, look at the THVD1450D (SOIC-8) if the VSSOP footprint is not required. For a lower-speed drop-in, the THVD1420 (20 Mbps) shares the same pinout and supply range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/THVD1450DGK","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/THVD1450DGK when reusing this data.
