Working Principles

The M74HC540RM13TR operates by receiving input signals on its A1-A8 pins and providing corresponding buffered outputs on its Y1-Y8 pins. The OE (Output Enable) pin controls the 3-state outputs, allowing them to be either active or in a high-impedance state. When the OE pin is low, the outputs are enabled and actively driven. Conversely, when the OE pin is high, the outputs enter a high-impedance state, effectively disconnecting them from the circuit.
