Working Principles

The MC74ACT32DR2G is a quad 2-input OR gate that performs logical OR operations on two input signals. It utilizes ACT (Advanced CMOS Technology) to achieve high-speed operation while maintaining low power consumption. The Schmitt-trigger inputs provide hysteresis, ensuring reliable switching even in the presence of noise.

When both inputs are low (logic 0), the output is also low. If either or both inputs are high (logic 1), the output becomes high. This behavior follows the truth table for an OR gate:

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