Working Principles
The PI90LV048AL is designed to translate logic signals between different voltage levels. It utilizes a bidirectional buffer architecture, allowing seamless communication between two logic domains. The device operates by monitoring the input signal levels and translating them to the corresponding output voltage levels. The direction of translation is controlled by the DIR pin. When enabled, the PI90LV048AL translates signals from A-side to B-side, and when disabled, it performs the translation in the opposite direction.
