Gates Logic

Logic gates are the standard digital logic gates you can find on a circuit board. They all do simple binary tasks, and therefore only have one output.

OR  
AND  
NOT  
NAND  
NOR  
XOR  
XNOR  

OR
Inputs: Type-Number A B C D E F G H
Outputs: Type-Number Out
Description: Returns 1 if any input is 1. Returns 0 if no inputs are 1.
Truth Table
Input 1 Input 2 Output
0 0 0
1 0 1
1 1 1

AND Inputs: Type-Number.png A B C D E F G H Outputs: Type-Number.png Out Description: Returns 1 only if all inputs are 1, otherwise returns 0. Truth Table Input 1 Input 2 Output 0 0 0 1 0 0 1 1 1

NOT Inputs: Type-Number.png A Outputs: Type-Number.png Out Description: Returns 1 if input is 0. Returns 0 if input is 1. Truth Table Input Output 0 1 1 0

NAND Inputs: Type-Number.png A B C D E F G H Outputs: Type-Number.png Out Description: Equivalent to adding a NOT to an AND. Returns 0 if all inputs are 1. Returns 1 if any inputs are 0. Truth Table Input 1 Input 2 Output 0 0 1 1 0 1 1 1 0

NOR Inputs: Type-Number.png A B C D E F G H Outputs: Type-Number.png Out Description: Equivalent to adding a NOT to an OR. Returns 0 if any inputs are 1. Returns 1 if all inputs are 0. Truth Table Input 1 Input 2 Output 0 0 1 1 0 0 1 1 0

XOR Inputs: Type-Number.png A B C D E F G H Outputs: Type-Number.png Out Description: Exclusive OR. Returns 1 if only one input is 1. Returns 0 if all inputs are 0 or more than one input is 1. Truth Table Input 1 Input 2 Output 0 0 0 1 0 1 1 1 0

XNOR Inputs: Type-Number.png A B C D E F G H Outputs: Type-Number.png Out Description: Equivalent to adding a NOT to an XOR. Returns 0 if only one input is 1. Returns 1 if all inputs are 0 or more than one input is 1. Truth Table Input 1 Input 2 Output 0 0 1 1 0 0 1 1 1
