Logic Gate Symbols - OR, AND, NOT, NOR, NAND, XOR, XNOR



In digital electronic circuits, logic gates are the basic fundamental component or building blocks. Every digital circuit, devices are consists of logic gates. Logic gates have one or multiple inputs and one output. Generally, logic gates are made of transistors. In this article, we are going to see the symbol of logic gates.


AND Gate Symbol


An AND gate has a minimum of two inputs. The output of the AND gate will be high when both of the input is high. If anyone input is low the output also be low. Here, you can see the symbol of AND Gate.

AND Gate Symbol, symbol of AND Gate




OR Gate Symbol


An OR Gate also has a minimum of two inputs. The output of the OR Gate will be high when anyone input is high. The output will be low when both of the inputs is low. Here, you can see the symbol of OR Gate.

NOT Gate Symbol


A NOT gate is also known as an inverter. It has a single input and a single output. When the input of the NOT gate is high the output will be low and vice versa. Here, you can see the symbol of NOT Gate.

NAND Gate Symbol


NAND gate is the combination of AND Gate and NOT gate. It also has a minimum of two inputs and one output. The output of the NAND Gate will be high when anyone input is low. The output will be low when both of the inputs are high. Here, you can see the symbol of NAND Gate.

NOR Gate Symbol


A NOR Gate is the combination of OR Gate and NOT Gate. NOR gate also have a minimum of two inputs and one output. The output of the NOR gate will be high when both of the input is low. The output of the NOR gate will be low when anyone input is low. Here, you can see the symbol of NOT Gate.

XOR Gate Symbol


XOR gate also has two inputs and one output. Here, you can see the symbol of XOR Gate.

XNOR Gate Symbol


XNOR Gate also has two inputs and one output. Here, you can see the symbol of XNOR Gate.
