Can Logic Gates Have Three Inputs?
Key Takeaways

Logic gates with three inputs are called threeinput logic gates.

There are eight different types of threeinput logic gates.

Threeinput logic gates can be used to implement a variety of logic functions.

Threeinput logic gates are commonly used in digital circuits.

The truth table for a threeinput logic gate can be used to determine its output for any given combination of inputs.
Introduction
Logic gates are electronic circuits that perform logical operations on one or more input signals to produce an output signal. The most common logic gates are twoinput logic gates, which have two input signals and one output signal. However, there are also logic gates with three or more inputs. Threeinput logic gates are called threeinput logic gates.
Types of ThreeInput Logic Gates
There are eight different types of threeinput logic gates. These gates are:

AND gate

OR gate

NAND gate

NOR gate

XOR gate

XNOR gate

ANDORINVERT gate

ORANDINVERT gate

Truth Tables for ThreeInput Logic Gates
The truth table for a threeinput logic gate shows the output of the gate for every possible combination of inputs. The truth table for a threeinput AND gate is shown below:
Input AInput BInput COutput00000010010001101000101011001111
As you can see from the truth table, the output of a threeinput AND gate is only 1 when all three inputs are 1.
Conclusion
Threeinput logic gates are a versatile type of logic gate that can be used to implement a variety of logic functions. These gates are commonly used in digital circuits to perform a variety of tasks.
