Protocol support for RS-485 and RS-422 means it fits both multi-drop (RS-485) and point-to-point (RS-422) topologies, common in factory automation, building management, and vehicle networks. ## AEC-Q100 and 125°C junction rating Active product status means TI continues to manufacture and support this device — no last-time-buy risk for production programs currently using it.","metaTitle":"SN65HVD1782QDRQ1 RS-485/422 Transceiver, AEC-Q100, 10 Mbps","metaDescription":"TI SN65HVD1782QDRQ1 half-duplex RS-485/422 transceiver, 3.3V–5V supply, 10 Mbps, AEC-Q100, -40°C to 125°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"10Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3.3V ~ 5V","Base Product Number":"65HVD1782","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":"$6.4600","priceTiers":[{"qty":1,"price":"$6.46000","currency":"USD"},{"qty":10,"price":"$5.80000","currency":"USD"},{"qty":25,"price":"$5.48320","currency":"USD"},{"qty":100,"price":"$4.75200","currency":"USD"},{"qty":250,"price":"$4.50832","currency":"USD"},{"qty":500,"price":"$4.04532","currency":"USD"},{"qty":1000,"price":"$3.44850","currency":"USD"},{"qty":2500,"price":"$3.44850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c721bafdb9c96114f81f1d92d04a099a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD1782QDRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is SN65HVD1782QDRQ1 compatible with 5V supply?","answer":"Yes, the SN65HVD1782QDRQ1 operates from a 3.3V to 5V supply, so it works directly on a 5V bus rail without external regulation."},{"question":"What is the difference between SN65HVD1782QDRQ1 and SN65HVD1782DR?","answer":"The SN65HVD1782QDRQ1 is the AEC-Q100 automotive-qualified version of the base SN65HVD1782DR.
