Working Principles

The SN74AVC1T45DCKT utilizes a combination of MOSFETs and level-shifting circuitry to achieve bi-directional voltage translation. When the OE (Output Enable) pin is high, the device is enabled, and the input signal on pin A is translated to the output pin B or vice versa, depending on the voltage levels. The VCCA pin sets the voltage level for Translator A.
