Working Principles

The SN74LVTH16244AZQLR is a logic level translator that allows communication between integrated circuits operating at different voltage levels. It uses a combination of input buffers, output drivers, and control circuitry to achieve this translation.

When the OE (Output Enable) pin is high, the outputs are in a high-impedance state, allowing other devices to drive the bus. When the OE pin is low, the inputs are translated to the corresponding output voltage levels based on the supply voltage.

The device operates within a specified supply voltage range and provides fast switching times to ensure efficient data transfer between different voltage domains.
