Working Principles

The 74HC125D,653 operates by receiving input signals on its four input pins (A1-A4). These signals are then buffered and driven to the corresponding output pins (Y1-Y4). The output enable pin (OE) controls whether the outputs are active or in a high-impedance state. When OE is high, the outputs are enabled and reflect the input signals. When OE is low, the outputs are disabled and enter a high-impedance state.
