TXB0108 in TXS0108 / BSS138 Level Shifters Family
The TXB0108 family from Texas Instruments consists of 8-bit bidirectional voltage-level translators that do not require a direction-control signal. Utilizing an auto-sensing architecture, these devices facilitate seamless communication between different logic-level domains ranging from 1.2 V to 3.6 V and 1.65 V to 5.5 V. They are designed specifically for push-pull CMOS outputs, making them a staple for interfacing modern low-voltage microcontrollers with legacy peripherals or diverse sensor ecosystems in complex embedded environments.

Variants within the TXB0108 sub-family primarily differ by their physical packaging and temperature qualifications. Available packages range from the standard TSSOP (PW) and SOIC to space-constrained VFBGA (GXY) and UQFN (RGY) footprints. Additionally, automotive-grade versions (TXB0108-Q1) are available, providing AEC-Q100 qualification and extended temperature ranges for harsh environment operation, while the core electrical translation characteristics remain consistent across the series.
