The 14-VDFN exposed-pad package with wettable flank (14-VSON 4.5x3) supports automated optical inspection (AOI) after reflow, a requirement in high-volume automotive assembly. No official successor has been announced, and the base product number TCAN1043 indicates a stable family. ## Package and mounting for automotive reflow Surface-mount in a 14-VDFN exposed pad (14-VSON 4.5x3). The wettable flank option improves side-wetting inspection, which is often a PPAP gate for tier-one suppliers.","metaTitle":"TCAN1043DMTTQ1 CAN Transceiver, AEC-Q100, 2 Mbps","metaDescription":"Texas Instruments TCAN1043DMTTQ1 CAN transceiver, AEC-Q100 qualified, 2 Mbps data rate, half-duplex, 4.5V to 5.5V supply, -55°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"CAN","Data Rate":"2Mbps","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"14-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"TCAN1043","Receiver Hysteresis":"120 mV","Operating Temperature":"-55°C~125°C(TA)","Supplier Device Package":"14-VSON (4.5x3)","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9767","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/90d91ae909f923fae37b71ca60ef3212.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TCAN1043DMTTQ1/alternatives.json"},"ai":{"faq":[{"question":"Can TCAN1043DMTTQ1 directly replace TCAN1042 or other CAN transceivers?","answer":"The TCAN1043DMTTQ1 is a pin-compatible upgrade within the TCAN104x family. It adds CAN FD support at 2 Mbps and includes the wettable flank package option. For a direct drop-in replacement, verify the pinout against the TCAN1042 datasheet; the base footprint is shared across the family."},{"question":"Does TCAN1043DMTTQ1 support CAN FD or only classical CAN?","answer":"The TCAN1043DMTTQ1 supports both classical CAN and CAN FD frames, with a data rate of 2 Mbps. This covers the typical CAN FD payload phase rates used in automotive networks."},{"question":"Is TCAN1043DMTTQ1 compatible with 5V microcontrollers?","answer":"Yes. The supply voltage range is 4.5V to 5.5V, which matches the VCC rail of standard 5V automotive microcontrollers. The logic interface levels are referenced to the supply, so no level shifting is needed."},{"question":"What is the difference between TCAN1043DMTTQ1 and TCAN1043DRQ1?","answer":"Both are AEC-Q100 CAN transceivers with the same base die. The TCAN1043DMTTQ1 uses a 14-VSON (4.5x3) package with wettable flank, while the TCAN1043DRQ1 uses a standard 14-SOIC package. The wettable flank option on the DMTT variant enables AOI inspection after reflow, which is often required for automotive PPAP."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TCAN1043DMTTQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TCAN1043DMTTQ1 when reusing this data.
