Logic gates are the fundamental block of almost every electronic component. Based on Boolean Logic, these gates produce outputs corresponding to different input combinations. When designing an electronic circuit, it’s essential to understand the application of each gate in order to pick one that meets your design requirements.
In this blog, we’ve compiled a list of some of the most commonly used logic gates and their applications.
The AND Gate
A fundamental logic gate, the AND gate only produces output at high input states. The working of this gate can be understood from the truth table that follows; the output will only appear high if all the inputs are at a high stage and will not appear otherwise.
The OR Gate
This digital logic gate results in a high output state as long as any of the input is at a high state. As shown in the truth table below, the gate outputs logic 1 when any one or both of the inputs are at a high state. The only time when the OR gate produces a low output is when both the inputs are at a low state.
The NOT Gate
As the name suggests, the gate is designed to produce an inverted output. If the input is at logic 1, the output will be at logic 0 and vice versa.
Derived Logic Gates
The aforementioned gates are just the basic logic gates; these can then be implemented in combination to create derived logic gates like the NAND and NOR gates.
The NAND Gate
As discussed above, the NAND gate produces an output that’s a combined result of the AND gate and NOT gates. To further understand how it works, let’s take a look at the truth table below:
Unlike the AND gate, which produces a low output when any of the inputs are high, the NAND gate produces a high output whenever any, or both of the inputs are low. The only time when the NAND gate produces a 0 logic is when both the inputs stand at 1.
The NOR Gate
A combination of the OR and NOT gates, the NOR gate produces an output that’s opposite of the OR gate.
The gate outputs logic 0 whenever its inputs are at logic 1. The only condition for the output to be at a high state is when both the inputs are at a low state.
Logic gates are used as building blocks for almost all digital components including phones, computers, fans, and traffic lights.
