CMOS XNOR gate

The CD4077 DIP Quad Exclusive-NOR Gate is a CMOS IC that contains four independent Exclusive-NOR gates, ideal for use in parity checkers, error detection systems, digital signal processing, and combinational logic circuits. Each gate produces a logic high (1) when the inputs are the same and a logic low (0) when the inputs differ. The IC offers low power consumption, high noise immunity, and operates within a wide voltage range (3V to 18V), packaged in a DIP-14 format for easy integration into breadboards and PCBs.
