Working Principles

The CD74AC541MG4 is designed to buffer and drive signals in digital circuits. It takes input signals from the A1-A7 pins and amplifies them to a level suitable for driving external loads. The OE (Output Enable) pin controls the output state of the device. When OE is low, the outputs (Y1-Y8) are active and reflect the input signals. When OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.
