CD4077 Quad 2-Input XNOR Gate IC DIP-14 (CD4077 DIP IC)
The CD4077 is a CMOS quad 2-input exclusive NOR gate IC consisting of four independent XNOR gate circuits in a single package. Each gate produces a high output only when both of its inputs are at the same logic level making it ideal for equality comparison and parity checking operations.
This IC is widely used in digital comparators, parity generators and checkers, error detection circuits, and combinational logic designs where exclusive NOR logic operations are required. It is commonly used in arithmetic circuits, data comparison systems, Arduino projects, and digital electronics where signal equality checking and bit manipulation are needed.
