It handles bidirectional data flow with 3-state outputs, making it suitable for bus isolation and level shifting in automotive ECUs, sensor interfaces, and infotainment systems. Automotive-grade qualification per AEC-Q100 means the part has passed the reliability stress tests required for under-hood and cabin electronics — temperature cycling, ESD, latch-up, and extended high-temperature operating life. The -40°C to 125°C operating range covers the full automotive ambient envelope. ## Supply range and drive capability across voltage domains The supply voltage range of 0.65V to 3.6V on both VCCA and VCCB rails lets the transceiver interface between sub-1V core logic (0.65V to 0.95V) and legacy 1.8V, 2.5V, or 3.3V peripheral buses. This covers the voltage translation needs in mixed-voltage automotive architectures where a low-voltage MCU talks to a 3.3V sensor or actuator. Output drive capability is 12mA for both high and low levels. That is sufficient for driving CMOS inputs on the same board or short PCB traces, but not for long backplane buses or high-capacitance loads — plan a buffer if the fan-out exceeds a few gates per line. The single-element 8-bit configuration with 3-state outputs allows the bus to be isolated when the transceiver is disabled, preventing contention during power sequencing or when multiple drivers share the same line. ## 24-VFQFN package with exposed thermal pad — PCB layout considerations The 24-VFQFN Exposed Pad package (5.5x3.5mm body) requires a thermal pad on the PCB for heat dissipation. The exposed paddle must be soldered to a copper plane — preferably connected to ground — to keep the junction temperature within limits during high-speed operation at 125°C ambient. Surface-mount assembly with a VFQFN footprint demands careful stencil design and reflow profiling. The package is moisture-sensitive; follow the MSL rating on the reel label for bake requirements before rework.","metaTitle":"TI CAXC8T245QWRGYRQ1 8-bit Translation Transceiver, AEC-Q100","metaDescription":"Texas Instruments CAXC8T245QWRGYRQ1 8-bit bidirectional translation transceiver, AEC-Q100 automotive grade, 0.65-3.6V supply, -40 to 125°C.","metaKeywords":null},"attributes":{"series":"74AXC","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Grade":"Automotive","Series":"74AXC","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"Translation Transceiver","Output Type":"3-State","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"24-VFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"0.65V ~ 3.6V","Number of Elements":"1","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"24-VQFN (5.5x3.5)","Current - Output High, Low":"12mA, 12mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.73","priceTiers":[{"qty":1,"price":"$1.73000","currency":"USD"},{"qty":10,"price":"$1.55500","currency":"USD"},{"qty":25,"price":"$1.46680","currency":"USD"},{"qty":100,"price":"$1.24980","currency":"USD"},{"qty":250,"price":"$1.17352","currency":"USD"},{"qty":500,"price":"$1.02682","currency":"USD"},{"qty":1000,"price":"$0.85080","currency":"USD"},{"qty":3000,"price":"$0.74038","currency":"USD"},{"qty":6000,"price":"$0.71296","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/05699e77f245bb33f15b72efa0800b2a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CAXC8T245QWRGYRQ1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CAXC8T245QWRGYRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CAXC8T245QWRGYRQ1 when reusing this data.
