Working Principles

The 74ACT541PC operates by receiving input signals on its eight data input pins (A1-A8). These signals are then amplified and buffered by the internal circuitry. The output enable pin (OE) controls whether the outputs (Y1-Y8) are active or in a high-impedance state. When the OE pin is low, the outputs are enabled and reflect the input signals. Conversely, when the OE pin is high, the outputs are disabled and enter a high-impedance state.
