CD4077 Quad 2-Input XNOR Gate IC

The CD4077 is a CMOS quad 2-input XNOR gate logic IC, delivering four independent XNOR gates in a single compact DIP-14 package. Designed for a wide operating voltage range, this IC is a reliable choice for digital logic design, Boolean algebra experiments, signal comparison circuits, and error detection systems.

Each gate produces a HIGH output when both inputs are identical, making it invaluable for equality checking, parity generation, and combinational logic applications. Its CMOS construction ensures ultra-low power consumption, making it well suited for battery-powered and portable electronic projects.

Compatible with the 4000 series CMOS logic family, the CD4077 interfaces easily with microcontrollers, FPGAs, and other TTL or CMOS devices. It is an excellent component for electronics students, hobbyists, and engineers prototyping digital circuits on breadboards or custom PCBs.
