Working Principles

The MC74VHCT244ADWR2 is a voltage level shifter that converts signals from one voltage domain to another. It consists of eight non-inverting buffer/line driver channels. When the enable (OE) input is high, the outputs are active and reflect the inputs. Conversely, when OE is low, the outputs are in a high-impedance state, effectively disconnecting them from the inputs.
