Working Principles

The PI74AVC164245AE is a bidirectional voltage translator that allows seamless communication between two different voltage domains. It uses a combination of MOSFETs and level-shifting circuitry to convert signals from one voltage level to another.

The direction of signal flow is controlled by the OE (Output Enable) pins. When the OE pin is low, the device is enabled, and the data can be transmitted bidirectionally. When the OE pin is high, the device is disabled, and the data lines are in a high-impedance state.

The IC operates with a supply voltage ranging from 1.2
