• May not be suitable for complex logic circuits requiring multiple gates.

Working Principles

The 74AHCT1G00GV-Q100H operates based on the principles of CMOS (Complementary Metal-Oxide-Semiconductor) technology. It utilizes a combination of NMOS (N-channel Metal-Oxide-Semiconductor) and PMOS (P-channel Metal-Oxide-Semiconductor) transistors to achieve the desired logical functionality.

When both input signals (A and B) are at logic level 1, the NMOS transistors in the NAND gate are turned on, creating a low resistance path from the output to ground. This pulls the output voltage down to logic level 0. In all other cases, at least one of the input signals is at logic level 0, causing the output to be pulled up to logic level 1.

Detailed Application Field Plans
