Working Principles

The SN74LVCC3245ADWRE4 operates by receiving data from one voltage domain and translating it to the appropriate voltage level for another domain. The direction of data flow is controlled by the DIR pin. When the DIR pin is set to a specific logic level, the IC acts as a bidirectional level shifter, allowing data to be transmitted in both directions. The OE pins control the output enable function, enabling or disabling the 3-state outputs.
