The 8 Mbps rating covers the faster data phase of CAN FD frames, so this part can be used in designs that need to move beyond the 1 Mbps ceiling of traditional CAN. The receiver hysteresis of 100 mV helps reject noise on the bus, which is important for signal integrity at these higher speeds, especially in electrically noisy automotive environments. ## Dual-channel architecture — two independent CAN interfaces in one package With two drivers and two receivers (2/2), the TCAN1046DMTRQ1 provides two independent CAN channels in a single 14-VSON package. This is useful for designs that need to connect two separate CAN buses (e.g., a primary and a secondary bus for redundancy, or a gateway node bridging two CAN segments). Compared to using two single-channel transceivers, this dual-channel approach saves board area and reduces component count. The full-duplex capability per channel means each channel can transmit and receive simultaneously, which is standard for CAN transceivers but worth noting for engineers new to the protocol. ## Supply range and operating conditions The 5 V supply is typical for CAN PHY layers, and the 4.5 V minimum gives some headroom for supply droop during cranking events. ## Package and mounting for automotive assembly The TCAN1046DMTRQ1 comes in a 14-VDFN package with an exposed pad (also designated as 14-VSON 4.5x3). The exposed pad provides a low thermal resistance path to the PCB, which helps dissipate heat when the transceiver is driving the bus at high data rates. The package supports surface-mount assembly with wettable flanks, which improves solder joint inspection (AOI) and reliability in automotive production. The ROHS3 compliance ensures it meets the latest environmental restrictions for automotive and consumer markets.","metaTitle":"TCAN1046DMTRQ1 CAN Transceiver, 8 Mbps, AEC-Q100, 14-VSON","metaDescription":"TI TCAN1046DMTRQ1 is a full-duplex CAN transceiver with 2/2 drivers/receivers, 8 Mbps data rate, AEC-Q100 qualified, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"CAN","Data Rate":"8Mbps","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"14-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5 ~ 5.5V","Base Product Number":"TCAN1046","Receiver Hysteresis":"100 mV","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"14-VSON (4.5x3)","Number of Drivers/Receivers":"2/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3600","priceTiers":[{"qty":1,"price":"$2.36000","currency":"USD"},{"qty":10,"price":"$2.12400","currency":"USD"},{"qty":25,"price":"$2.00320","currency":"USD"},{"qty":100,"price":"$1.70690","currency":"USD"},{"qty":250,"price":"$1.60272","currency":"USD"},{"qty":500,"price":"$1.40238","currency":"USD"},{"qty":1000,"price":"$1.16197","currency":"USD"},{"qty":3000,"price":"$1.13400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/74f316740729413b86529b9845da5585.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TCAN1046DMTRQ1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TCAN1046DMTRQ1 and how is it priced?","answer":"The TCAN1046DMTRQ1 is available to order through independent distribution.
