CD4072 Dual 4-Input OR Gate

The CD4072 is a dual 4-input OR gate from the 40xx series CMOS logic family. This device contains two independent 4-input OR gates, each generating a high output if one or more of its four inputs are high. The CD4072 is a standard combinational logic component for systems requiring wide OR gating.

Each gate implements the Boolean function Y = A+B+C+D. The CD4072 is useful for combinational logic, enable circuits, and as a building block in larger logic functions. Standard CMOS features include wide supply voltage range, low power consumption, and high noise immunity.
