The OR logic gate has how many inputs?

The OR logic gate is a fundamental component in digital electronics that performs a specific logical operation. It produces a true output (or a high signal) if at least one of its inputs is true (or high). While the OR gate can technically handle a variable number of inputs, the most common configuration features two inputs.

In practical applications, a two-input OR gate is frequently used in circuits, allowing for straightforward calculations and integrating multiple signals. If either of the two inputs receives a true (1) signal, the output will also be true (1). This behavior makes it crucial for various logical functions in computing and digital systems.

Higher-input OR gates, such as those with three or four inputs, exist, but they are extensions of this basic two-input design. The standard two-input version remains the most prevalent for understanding the fundamental operation of OR gates.
