Working Principles

The SN74HCT244NSRG4 is a non-inverting octal buffer/line driver. It takes input signals from the A1 to A7 pins and amplifies them to drive corresponding outputs Y1 to Y8. The OE (Output Enable) pin controls the state of the outputs. When OE is low, the outputs are enabled and reflect the input signals. When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus.
