Working Principles

The SN74LVC2T45DCURG4 operates by receiving input signals from one logic family and translating them into appropriate voltage levels for another logic family. The direction of translation is automatically controlled based on the OE pin's state. When OE is low, the IC functions as a bidirectional level shifter, allowing data to flow between the A and B channels. Conversely, when OE is high, the IC isolates the A and B channels, preventing any data transfer.
