Working Principles

The CD74HCT00MG4 is based on CMOS technology, which combines both NMOS and PMOS transistors to achieve low power consumption and high noise immunity. Each NAND gate within the IC consists of two inputs (A and B) and one output (Y). The output Y is the logical NAND of the inputs A and B. When both inputs are high (logic level 1), the output becomes low (logic level 0). In all other cases, the output remains high.

Detailed Application Field Plans

The CD74HCT00MG4 is widely used in various digital systems and electronic devices that require logic operations. Some common application areas include:

1. Microcontrollers and Microprocessors
