Working Principles

The TXB0108RGYR utilizes a combination of MOSFETs and control circuitry to achieve voltage level translation. When an input signal is received on one side (Side A), the integrated circuit translates the voltage level to the corresponding logic level on the other side (Side B). The direction of translation is determined by the Output Enable (OE) pin.

The control circuitry ensures that the voltage levels are properly translated, while the MOSFETs act as switches to connect or disconnect the input and output channels. This allows bidirectional data transmission between systems with different logic voltage levels.
