Working Principles

The SN74F541DWR operates by receiving input signals on its eight input pins (A1-A8). These signals are then buffered and non-inverted before being transmitted to the corresponding output pins (Y1-Y8). The output enable pins (OE1 and OE2) control the state of the outputs, allowing them to be either active or in a high-impedance state.

When the output enable pins are active, the buffered input signals are transferred to the outputs. Conversely, when the output enable pins are inactive, the outputs enter a high-impedance state, effectively disconnecting them from the bus lines.
