Working Principles

The NLV74HC540ADTR2G operates by receiving digital input signals on its input pins (A1-A4) and providing buffered output signals on the corresponding output pins (Y1-Y4). The 3-state outputs allow the device to be effectively connected to a bus, enabling multiple devices to share the same communication lines without interference.

When the Output Enable (OE) pin is high, the outputs are enabled and reflect the input signals. Conversely, when the OE pin is low, the outputs are in a high-impedance state, effectively disconnecting them from the bus.

The Schmitt-trigger inputs ensure reliable switching between logic levels, even in the presence of noise or signal degradation.
