CD4081 Quad 2-Input AND Gate

The CD4081 is a quad 2-input AND gate from the 40xx series CMOS logic family. This device contains four independent 2-input AND gates, each generating a high output only when both of its inputs are high. The CD4081 is a standard building block for digital logic systems, offering reliable AND gating with the characteristic benefits of CMOS: wide supply range, low power, and high noise immunity.

Each gate implements the Boolean function Y = A·B. These gates can be used individually or combined to implement more complex logic functions. The CD4081 is commonly used in control circuits, gating of digital signals, and enable logic in microprocessor and peripheral systems.
