Working Principles

The 74LVC125ABQ,115 IC works by receiving digital input signals on the A1 to A4 pins. These signals are then amplified and buffered by the internal circuitry. The output signals (Y1 to Y4) can be enabled or disabled using the OE# pin. When the OE# pin is low, the outputs are active and reflect the input signals. When the OE# pin is high, the outputs are put into a high-impedance state, allowing other devices to drive the bus.
