Working Principles

The TXB0104GXUR utilizes a voltage level shifting technique to translate logic signals between different voltage domains. It employs a combination of MOSFETs and level shifters to ensure bidirectional communication while maintaining signal integrity.

When a logic signal is applied to one side of the translator, the circuit automatically detects the voltage level and translates it to the corresponding level on the other side. The direction of translation is determined by the input signal, eliminating the need for additional control signals.
