Working Principles

The SN74LVC863ADWRE4 utilizes a combination of MOSFETs and level-shifting circuitry to achieve voltage translation. The DIR pin controls the direction of translation, while the OE pin enables or disables the outputs. When the DIR pin is set to logic high, the voltage is translated from voltage domain A to voltage domain B, and vice versa when the DIR pin is set to logic low. The internal circuitry ensures that the translated signal maintains its logic levels within the specified voltage ranges.
