IC Logic Gate CD4081BE Quad 2-Input And Gate

The CD4081 is a CMOS-based logic IC that contains four independent 2-input AND gates. Each gate outputs HIGH only when all its inputs are HIGH, making it ideal for digital logic circuit design. Belonging to the CD4000 series, the CD4081 features low power consumption, wide voltage operation, and high noise immunity.

How AND Gate Works:

An AND gate outputs HIGH only when all of its inputs are HIGH. Below is the truth table of a 2-input AND gate:

Input A Input B Output Q
0 0 0
1 0 0
0 1 0
1 1 1
