TXS0106EPWR in TXS0108 / BSS138 Level Shifters Family
The TXS0106EPWR is a 6-bit bidirectional voltage level translator designed by Texas Instruments for multi-voltage digital signal interfacing. Unlike traditional directional translators, it uses an auto-sensing architecture with integrated pull-up resistors, making it specifically suited for both open-drain and push-pull applications. It bridges the gap between low-voltage processors and higher-voltage peripherals, supporting a wide range of logic levels from 1.2V up to 3.6V on the A-port and 1.65V to 5.5V on the B-port.
Within this sub-family, variants primarily differ by channel count, such as the 4-bit TXS0104 or 8-bit TXS0108, and packaging options like TSSOP, VQFN, or wafer-level chip scale (DSBGA). Certain 'E' suffixes indicate enhanced ESD protection or specific temperature ratings. While the core translation architecture remains consistent, engineers must select the specific variant that matches their required I/O count to optimize board space and minimize parasitic capacitance.
