Working Principles

The PI74LPT16374AAE is a logic level translator that facilitates communication between devices operating at different voltage levels. It utilizes a bidirectional voltage translation technique, allowing signals to be translated from one voltage domain to another.

The IC consists of eight separate ports, each with its own data input, data output, enable input, voltage supply input, and voltage supply output pins. The enable inputs control the direction of data flow, enabling or disabling the translation process for each port independently.

By applying appropriate voltage levels to the voltage supply inputs (VCCA) and voltage supply outputs (VCCB), the PI74LPT16374AAE translates the logic levels of incoming signals from one voltage domain to the corresponding levels in the other domain. This enables seamless communication between devices operating at different voltage levels.
