It remains a current-production choice for new CAN bus nodes in automotive and industrial equipment, and no successor part has been announced that would force a redesign. ## Supply rail and logic-level consideration The CAN bus pins are 5 V tolerant. For designs using a 3.3 V microcontroller, the TCAN1043DQ1's logic input thresholds are referenced to its 5 V supply — a level-shifter or a 5 V-tolerant MCU I/O is needed on the TXD/RXD lines. The part does not include an integrated VIO pin for 3.3 V logic compatibility.","metaTitle":"TCAN1043DQ1 CAN Transceiver, AEC-Q100, 2 Mbps","metaDescription":"Texas Instruments TCAN1043DQ1 CAN transceiver, AEC-Q100 qualified, 2 Mbps data rate, 4.5 V to 5.5 V supply, -55°C to 125°C operating range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"-","Series":"Automotive, AEC-Q100","Package":"Tube","Protocol":"CANbus","Data Rate":"2Mbps","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"TCAN1043","Receiver Hysteresis":"50 mV","Operating Temperature":"-55°C~125°C","Supplier Device Package":"14-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/90d91ae909f923fae37b71ca60ef3212.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TCAN1043DQ1/alternatives.json"},"ai":{"faq":[{"question":"Does TCAN1043DQ1 work at 125°C?","answer":"The part is specified and qualified for continuous operation at 125°C ambient, which covers under-hood automotive and high-temperature industrial environments."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TCAN1043DQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TCAN1043DQ1 when reusing this data.
