Working Principles

The 74HC32D is a quad 2-input OR gate that performs logical OR operations on two input signals. It utilizes high-speed CMOS technology, which enables fast operation and low power consumption. The Schmitt-trigger action on all inputs ensures better noise immunity by allowing slow input transitions.

When both inputs of the OR gate are low (logic 0), the output will also be low. If any of the inputs is high (logic 1), the output will be 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 |
