What this level translator does for your bus
The TI CAXC4T245QWBQBRQ1 is a 4-bit bidirectional voltage-level translator from the 74AXC logic family, qualified to AEC-Q100 for automotive use. It translates signals between two independent supply rails, VCCA and VCCB, each ranging from 0.65 V to 3.6 V.
380 Mbps data rate — enough for high-speed serial
A data rate of 380 Mbps passes high-speed serial without introducing pulse-skew that closes timing margin.
Temperature range and automotive qualification
Rated for -40°C to 125°C ambient, this translator is intended for under-hood and engine-bay environments where the PCB sees wide thermal cycling. The AEC-Q100 qualification means it has passed the automotive stress tests: high-temperature operating life, temperature cycling, biased humidity, and ESD robustness. For a procurement engineer, this qualification simplifies the PPAP submission — the part already carries the automotive-grade data package.
Lifecycle and sourcing posture
It is RoHS3 compliant. For BOM planning, this part is available through independent distribution and is quoted to order against an RFQ — current pricing and lead time are confirmed at quote time.
