Working Principles

The SN74LVTH32244ZKER is designed to translate logic levels between different voltage domains. It utilizes a combination of MOSFETs and level-shifting circuitry to achieve bidirectional voltage translation. When an input signal from one voltage domain is applied, the IC translates it to the corresponding logic level in the target voltage domain. The non-inverting nature of the device ensures that the translated signal maintains its original logic state.
