It handles the physical-layer interface between a CAN protocol controller and the differential bus, operating at data rates up to 8 Mbps in half-duplex mode. ## Supply architecture and bus voltage tolerance The wide bus-side tolerance means the part can survive load-dump transients and battery-voltage excursions common in 12 V and 24 V vehicle electrical systems without external clamping. The 140 mV of receiver hysteresis provides noise margin on the differential bus lines, reducing false bit detection in electrically noisy environments. ## Package, footprint, and inspection The wettable flank allows automated optical inspection (AOI) of the solder joints after reflow, which is a practical advantage for high-volume automotive assembly lines where hidden solder defects under a standard QFN would escape visual check.","metaTitle":"TI TCAN1043ATDMTRQ1 CAN Transceiver, Automotive Grade","metaDescription":"Texas Instruments TCAN1043ATDMTRQ1 automotive CAN transceiver, half-duplex, 8 Mbps, AEC-Q100 qualified, 4.5-40V supply, 14-VSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"8Mbps","Mounting Type":"Surface Mount, Wettable Flank","Qualification":"AEC-Q100","Package / Case":"14-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V, 4.5V ~ 40V","Receiver Hysteresis":"140 mV","Operating Temperature":"-40°C ~ 150°C (TJ)","Supplier Device Package":"14-VSON (3x4.5)","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0900","priceTiers":[{"qty":1,"price":"$2.09000","currency":"USD"},{"qty":10,"price":"$1.87400","currency":"USD"},{"qty":25,"price":"$1.76760","currency":"USD"},{"qty":100,"price":"$1.50590","currency":"USD"},{"qty":250,"price":"$1.41400","currency":"USD"},{"qty":500,"price":"$1.23724","currency":"USD"},{"qty":1000,"price":"$1.02515","currency":"USD"},{"qty":3000,"price":"$0.81810","currency":"USD"},{"qty":6000,"price":"$0.78780","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ea8845c3e290ca4ac8118cbc9eaa570e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TCAN1043ATDMTRQ1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TCAN1043ATDMTRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TCAN1043ATDMTRQ1 when reusing this data.
