Working Principles

CD74HC125QPWRG4Q1 operates by receiving input signals through its four input pins (A, B, C, D). These signals are then buffered and amplified by the internal circuitry. The output pins (Y) provide the amplified signals, which can be controlled using the respective output enable pins (OE). When the OE pin is low, the corresponding output pin is active, allowing the signal to pass through. Conversely, when the OE pin is high, the output pin enters a high impedance state, effectively disconnecting it from the circuit.
