Working Principles

The PI3VT3245-ALE is a voltage translator IC that facilitates communication between two logic families operating at different voltage levels. It utilizes a bidirectional level-shifting technique to convert signals from one voltage domain to another. The direction of translation is controlled by the DIR pin, while the OEAB and OEBA pins enable or disable the translation function.

When the DIR pin is set to logic high, the A-side inputs are translated to the B-side outputs, and vice versa when the DIR pin is set to logic low. The OEAB and OEBA pins are used to enable or disable the translation function independently for each side. When both OEAB and OEBA are active, the translation is disabled, and the A-side and B-side remain isolated.
