The supply range of 4.5V to 5.5V is sized for a nominal 5V rail, but the 4.5V floor keeps the transceiver alive through cold-crank dips on a 12V or 24V vehicle battery—a common failure point for parts with tighter undervoltage lockout. The 120 mV receiver hysteresis adds noise margin on the differential bus, reducing false bit reception in electrically noisy environments like motor drives or ignition systems. This makes the TCAN1042HVDRQ1 a candidate for engine bay, transmission control, and brake-system modules where the ambient can exceed 105°C.","metaTitle":"TCAN1042HVDRQ1 CAN Transceiver, AEC-Q100, 2 Mbps, 8-SOIC","metaDescription":"Texas Instruments TCAN1042HVDRQ1 automotive CAN transceiver, AEC-Q100 qualified, 2 Mbps data rate, 4.5V–5.5V supply, -55°C to 125°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"-","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"CANbus","Data Rate":"2Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"TCAN1042","Receiver Hysteresis":"120 mV","Operating Temperature":"-55°C~125°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9e3fd7fc4cbd2061510f90cb0f717ea2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TCAN1042HVDRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TCAN1042HVDRQ1 AEC-Q100 qualified?","answer":"Yes, the TCAN1042HVDRQ1 is AEC-Q100 qualified, meaning it has passed automotive-grade stress tests for extended temperature, ESD, and latch-up, and is suitable for under-hood and chassis-domain applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TCAN1042HVDRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TCAN1042HVDRQ1 when reusing this data.
