TXB0108RUKR in TXS0108 / BSS138 Level Shifters Family
The TXB0108RUKR is a high-performance 8-bit bidirectional voltage-level translator from Texas Instruments, designed for interfacing digital signals between mismatched voltage domains. Unlike traditional shifters, it utilizes an auto-direction sensing architecture that eliminates the need for a direction control signal. It supports a wide range of operational voltages from 1.2V to 3.6V on Port A and 1.65V to 5.5V on Port B, making it a standard choice for modern multi-rail embedded systems.
Variants in This Sub-Family
Variants within the TXB0108 family primarily differ in their physical packaging and temperature ratings. While the RUKR suffix denotes the VQFN package, other versions like the TXB0108PWR use the TSSOP-20 format, which offers easier hand-soldering for prototyping. Some automotive-grade 'Q1' variants are available with AEC-Q100 qualification, offering higher reliability and extended temperature ranges for harsh environment deployments in vehicle telematics and engine control units.
