Working Principles

The 74AHCT1G14GW,165 operates based on the principles of complementary metal-oxide-semiconductor (CMOS) technology. It utilizes a combination of NMOS (N-type metal-oxide-semiconductor) and PMOS (P-type metal-oxide-semiconductor) transistors to achieve the desired logic inversion function.

When the input signal is high, the NMOS transistor conducts, allowing current to flow from the power supply (VCC) to the output pin (Y). Simultaneously, the PMOS transistor is turned off, preventing current flow to ground (GND). This results in a low logic level at the output.

Conversely, when the input signal is low, the NMOS transistor is turned off, blocking current flow to the output pin. At the same time, the PMOS transistor conducts, providing a path for current to flow from VCC to GND. As a result, a high logic level is produced at the output.
