TXS0101DBVR in TXS0108 / BSS138 Level Shifters Family
The TXS0101DBVR is a specialized 1-bit bidirectional voltage level translator manufactured by Texas Instruments. Designed for applications where mismatched logic levels prevent direct interfacing, this component utilizes a pass-gate architecture with internal pull-up resistors. It effectively bridges the gap between low-voltage processors and higher-voltage peripherals, supporting a range from 1.2V to 3.6V on Port A and 1.65V to 5.5V on Port B. This eliminates the need for a direction control signal, simplifying PCB layout and firmware complexity.
Variants in This Sub-Family
Variants within the TXS sub-family primarily differ in channel count, ranging from the single-channel TXS0101 to the eight-channel TXS0108. Packaging options also vary significantly, including small-form-factor SOT-23, SC70, and space-saving VFBGA or UQFN packages for high-density designs. Some variants are automotive-qualified (Q100), while others are optimized with different internal pull-up resistor values to balance speed versus power consumption in open-drain modes.
