Working Principles

The SN74ALVCF162834LR is designed to translate logic levels between two different voltage domains, typically used in mixed-voltage systems. It utilizes a bidirectional voltage level translation technique, allowing seamless communication between devices operating at different voltage levels.

The DIR pin controls the direction of translation. When DIR is set to logic low (0), the A port is connected to the B port, enabling translation from A to B. Conversely, when DIR is set to logic high (1), the B port is connected to the A port, facilitating translation from B to A.

The IC operates within a specified supply voltage range and provides ESD protection to safeguard against electrostatic discharge events. It offers high-speed performance with low propagation delay, ensuring efficient signal transmission between voltage domains.
