Working Principles

The SN74ALVC125PWE4 is a quad bus buffer gate that amplifies and buffers input signals. It operates by receiving input signals (A1-A4) and controlling the output signals (Y1-Y4) based on the control input (G1). When G1 is low, the outputs are in a high-impedance state, allowing multiple devices to share the same bus without interference. When G1 is high, the inputs are amplified and passed through to the outputs.
