Working Principles

The NLV74VHC125DR2G operates based on complementary metal-oxide-semiconductor (CMOS) technology. It utilizes a combination of transistors and logic gates to buffer and drive digital signals. When the enable pin (OE) is active, the inputs (A1-A4) are passed through the internal circuitry and appear at the corresponding outputs (Y1-Y4). When the enable pin is inactive, the outputs are disconnected from the circuit, entering a high-impedance state.
