Working Principles

The SN74LV125APW operates by receiving input signals through the A1-A4 pins. These signals are buffered and amplified by the internal circuitry. The G1-G4 pins control the output state of each buffer gate. When the enable input (G) is high, the corresponding output (Y) is active and reflects the input signal. When the enable input is low, the output is in a high-impedance state, allowing for bus sharing or isolation.
