Working Principles

The TXB0101DCKTG4 utilizes a combination of MOSFETs and level-shifting circuitry to achieve bidirectional voltage level translation. It detects the input signal levels and automatically determines the direction of data flow. When the input signal is at a higher voltage level than the output, the level shifter raises the voltage to match the desired level. Conversely, when the input signal is at a lower voltage level, the level shifter lowers the voltage accordingly.
