AND Gate (MA166E)

The output of an AND gate is in the high logic level only IF either input (A or B) is in the high logic level. Figure 1 shows the symbol of an AND gate and the equivalent circuits.


 

 

 

Equation 1

2-Input AND Gate

X = A.B

 

Where:

X is the output logic level

A and B are the input logic level
