The wide supply range of 4.5 V to 28 V covers 12 V and 24 V automotive battery systems with margin for load-dump transients, making it suitable for engine control units, body controllers, and ADAS sensor interfaces. The 5 Mbps data rate confirms CAN FD (flexible data-rate) support, allowing payloads larger than 8 bytes and faster arbitration-to-data phase transitions. This is a step up from classic CAN 2.0 parts limited to 1 Mbps. The receiver hysteresis of 135 mV provides noise immunity on the bus, important in automotive environments with alternator whine and motor drive coupling. For designs still using CAN 2.0 controllers, the TCAN1145DRQ1 drops back to 1 Mbps operation transparently. ## AEC-Q100 and 150°C junction — where it fits The combination of AEC-Q100 qualification and a 150°C junction temperature rating places this transceiver in the under-hood and engine-bay tier. It is not limited to cabin or chassis domains; the 150°C TJ covers exhaust-side sensors, turbocharger actuators, and transmission control modules where ambient temperatures exceed 125°C.","metaTitle":"TCAN1145DRQ1 CAN Transceiver, Automotive, 5 Mbps, AEC-Q100","metaDescription":"Texas Instruments TCAN1145DRQ1 automotive CAN transceiver, half-duplex, 5 Mbps CAN FD, 4.5 V to 28 V supply, AEC-Q100, -40°C to 150°C, 14-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Interface & Transceivers"],"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":"$3.1400","priceTiers":[{"qty":1,"price":"$3.14000","currency":"USD"},{"qty":10,"price":"$2.82400","currency":"USD"},{"qty":25,"price":"$2.67000","currency":"USD"},{"qty":100,"price":"$2.31420","currency":"USD"},{"qty":250,"price":"$2.19548","currency":"USD"},{"qty":500,"price":"$1.97000","currency":"USD"},{"qty":1000,"price":"$1.66145","currency":"USD"},{"qty":2500,"price":"$1.57838","currency":"USD"},{"qty":5000,"price":"$1.51904","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/46f4d5e0f18d50f0a8068a74fcf4d079.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TCAN1145DRQ1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TCAN1145DRQ1?","answer":"TCAN1145DRQ1 is available to order through independent distribution."},{"question":"Does TCAN1145DRQ1 support CAN FD?","answer":"Yes, the 5 Mbps data rate confirms CAN FD support.
