Working Principles

The MC74HC08ADR2G operates based on the principles of digital logic. It performs the logical AND operation on two input signals (A and B) and produces an output signal (Y) based on the following truth table:

| A | B | Y | |---|---|---| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 1 |

The gate uses CMOS technology to achieve high-speed operation and low power consumption. When both inputs are high (logic level 1), the output is also high. In all other cases, the output is low (logic level 0).
