Working Principles

SN74LVC2T45DCTRE4 operates based on a bidirectional voltage translation principle. It uses level-shifting circuitry to convert signals between two different voltage domains. The direction of translation is determined by the state of the DIR pin. When the DIR pin is high, the translation occurs from Channel A to Channel B, and vice versa when the DIR pin is low. The OE pin can be used to enable or disable the outputs as needed.
