The single driver and single receiver (1/1) handle the differential bus pair, and the 120 mV receiver hysteresis gives you a cleaner signal on a long or noisy twisted pair — useful when the harness runs across the vehicle. For a BOM line going into a multi-year vehicle program, that removes the single-source-obsolescence risk you would carry with an NRND or EOL part. ## Temperature range and package — field-fit for harsh spots That covers engine bay, transmission, and exhaust-adjacent locations where the ambient is well above 85°C. The 14-VSON (4.5x3) package with wettable flank supports automated optical inspection (AOI) on the assembly line — a practical advantage for high-volume production where you want to verify every solder joint.","metaTitle":"TCAN1043HGDMTTQ1 CAN Transceiver, 5 Mbps, AEC-Q100, Active","metaDescription":"Texas Instruments TCAN1043HGDMTTQ1 automotive CAN transceiver, 5 Mbps data rate, half-duplex, -55°C to 125°C, 14-VSON package.","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":"5Mbps","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/TCAN1043HGDMTTQ1/alternatives.json"},"ai":{"faq":[{"question":"Does TCAN1043HGDMTTQ1 support CAN FD and what is its maximum data rate?","answer":"Yes, the TCAN1043HGDMTTQ1 supports CAN FD with a maximum data rate of 5 Mbps. That is fast enough for the data phase of a CAN FD frame, which typically runs at 2 Mbps to 5 Mbps on the physical layer."},{"question":"What is the difference between TCAN1043HGDMTTQ1 and TCAN1042?","answer":"The TCAN1043HGDMTTQ1 is a 5 Mbps CAN FD transceiver, while the TCAN1042 is typically a 1 Mbps or 2 Mbps classic CAN transceiver. The 1043 also includes the wettable-flank package option for AOI inspection, which the older 1042 may not offer in all variants. Both are AEC-Q100 qualified and share a similar pinout, but the 1043 is the higher-speed, newer-generation part."},{"question":"Is TCAN1043HGDMTTQ1 compatible with 3.3V microcontrollers?","answer":"Its logic-level interface is 5 V tolerant, so you need level translation or a 5 V-tolerant MCU I/O if you are connecting to a 3.3 V microcontroller. A simple resistor divider or a 5 V-tolerant GPIO pin works for the TXD and RXD lines."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TCAN1043HGDMTTQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TCAN1043HGDMTTQ1 when reusing this data.
