In this blog, we will delve into the specifications and applications of the top five OR gate ICs commonly used by circuit designers. Understanding these ICs will empower you to make informed decisions when designing your circuits. So, let’s dive in!
What is OR Gate in simple terms and how it works
An OR gate is a fundamental logic gate that takes multiple input signals and produces an output based on the logical OR operation. In simple terms, an OR gate determines if at least one of its input signals is true (1), and if so, it outputs a true (1) signal. Otherwise, it outputs a false (0) signal.
The operation of an OR gate can be understood using a truth table. Consider an OR gate with two inputs, A and B. The truth table for the OR gate is as follows:
| Input A | Input B | Output |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
As seen in the truth table, the output of an OR gate is true (1) if at least one of the inputs is true (1). If both inputs are false (0), then the output is also false (0).
The OR gate can be represented using a logic symbol, which consists of a curved line with inputs on the left side and the output on the right side. The OR gate symbol is typically accompanied by the letter “OR” inside to indicate its function.
In electronic circuits, OR gates are realized using various technologies, such as transistors, diodes, or integrated circuits (ICs). These gates are building blocks for more complex logic functions and are widely used in digital systems, ranging from simple applications like switches and sensors to complex computing devices like microprocessors and memory units.
