It handles one driver and one receiver on a single differential bus pair, with the 50 mV receiver hysteresis that helps keep noise from long cable runs from triggering false start bits. ## 115 Kbps — enough for most sensor and actuator networks The data rate caps at 115 Kbps. That is fine for PLC-to-drive links, HVAC zone controllers, battery-monitor polling, or any Modbus RTU network running at 9600 or 38400 baud. If your design needs 1 Mbps or higher, this is not the part — look at the SN65HVD17xx family instead. But for the bulk of industrial fieldbus and automotive body-electronics traffic, 115 Kbps leaves margin.","metaTitle":"SN65HVD1780QDRQ1 RS485 Transceiver, AEC-Q100, 115 Kbps","metaDescription":"TI SN65HVD1780QDRQ1 half-duplex RS422/RS485 transceiver, AEC-Q100 qualified. 115 Kbps data rate, 3.15V-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":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS422, RS485","Data Rate":"115Kbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3.15V ~ 5.5V","Base Product Number":"65HVD1780","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C~125°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.6800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c721bafdb9c96114f81f1d92d04a099a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1780QDRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of SN65HVD1780QDRQ1?","answer":"The data rate is 115 Kbps, which covers standard industrial fieldbus speeds like 9600 and 38400 baud as well as Modbus RTU."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65HVD1780QDRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65HVD1780QDRQ1 when reusing this data.
