Rated at 5 Mbps, the TCAN1144DRQ1 supports CAN FD (flexible data-rate) frames, which allow payloads larger than the classical 8-byte limit and faster arbitration-to-data transitions. This matters when a design needs to push firmware updates or high-resolution sensor streams over the CAN bus without adding a second network. The half-duplex architecture keeps the pinout simple — one TXD, one RXD, and the CANH/CANL differential pair — matching the standard CAN physical layer footprint. ## AEC-Q100 and 150°C junction rating AEC-Q100 qualification covers the full automotive stress suite: high-temperature operating life, temperature cycling, moisture sensitivity, and ESD. The 150°C junction maximum extends the operating envelope beyond the typical 125°C grade, which is relevant for engine bay or exhaust-adjacent mounting where ambient temperatures push the silicon. No last-time-buy or end-of-life notification has been issued. For dual-sourcing or a pin-compatible alternate, the TCAN1145DRQ1 is a same-family variant — verify the specific feature set (e.g., wake-up pattern or INH pin) against the application requirements.","metaTitle":"TCAN1144DRQ1 CAN Transceiver, 5 Mbps, AEC-Q100, 14-SOIC","metaDescription":"Texas Instruments TCAN1144DRQ1 automotive CAN transceiver, half-duplex, 5 Mbps CAN FD, AEC-Q100, 4.5V-28V supply, -40°C to 150°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Grade":"Automotive","Duplex":"Half","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Protocol":"CANbus","Data Rate":"5Mbps","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 28V","Receiver Hysteresis":"135 mV","Operating Temperature":"-40°C ~ 150°C (TJ)","Supplier Device Package":"14-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7700","priceTiers":[{"qty":1,"price":"$2.77000","currency":"USD"},{"qty":10,"price":"$2.48600","currency":"USD"},{"qty":25,"price":"$2.34560","currency":"USD"},{"qty":100,"price":"$1.99860","currency":"USD"},{"qty":250,"price":"$1.87656","currency":"USD"},{"qty":500,"price":"$1.64200","currency":"USD"},{"qty":1000,"price":"$1.36052","currency":"USD"},{"qty":2500,"price":"$1.02262","currency":"USD"},{"qty":5000,"price":"$0.98475","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e54caecee3b8a139fe60383a835cce93.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TCAN1144DRQ1/alternatives.json"},"ai":{"faq":[{"question":"Does TCAN1144DRQ1 support CAN FD?","answer":"Yes, the 5 Mbps data rate rating confirms CAN FD support, enabling larger payloads and faster data phases beyond classical CAN."},{"question":"What is the difference between TCAN1144DRQ1 and TCAN1145DRQ1?","answer":"Both are same-family automotive CAN FD transceivers.
