Working Principles

The 74AVC1T45FW5-7 utilizes a combination of level-shifting circuitry and bidirectional transmission gates to achieve voltage level translation. The direction of data flow is controlled by the OE pin, which determines whether the A-side or B-side logic level is active. When the OE pin is high, the A-side logic level is active, and when it is low, the B-side logic level is active.

The level-shifting circuitry ensures that the input signals from one logic level are translated to the corresponding voltage level required by the other side. This enables seamless communication between devices operating at different logic voltage levels.
