Digital / Logic Circuit Symbols

- circuit symbols or circuit diagram symbols for logic elements including AND, OR, NAND, NOR, etc.

There is a vareity of different symbols for logic elements within a circuit. NAND, NOR and AND and OR are the most common circuit symbols, but oters are also used.

This page provides circuit symbols for logic elements.

The circuit symbols are based on those that appear to be most widely used.

Logic circuit symbols

The selection of logic circuit diagram symbols:



The symbol for a logic buffer block
Logic buffer

The circuit symbol for a logic inverter block with the small circle on the output indicating the inversion
Logic inverter

Symbol for an AND logic block showing the two inputs (there can be as many as required) and the single output
Logic AND gate

the NAND gate circuit symbol showing the small circle on the output to indicate the inversion. Two inputs are shown, but there can be as many as needed
Logic NAND gate

The circuit symbol for an OR gate showing two inputs and the one output. More inputs cna be added to the symbol as needed
Logic OR gate

The circuit symbol for a logic NOR function with the indication of the inverting function.
Logic NOR gate
