The CD4077 is a high-performance quad exclusive-NOR (XNOR) gate IC from the CD4XXX CMOS logic family, designed for precise digital comparison and logic processing in embedded, industrial, and communication systems. Built using advanced CMOS technology, it delivers ultra-low power consumption, high noise immunity, and stable switching performance, ensuring reliable operation across a wide range of electronic applications.
Operating over a wide supply voltage range of 3V to 15V, the CD4077 provides excellent design flexibility compared to lower-voltage logic families. This wide operating range allows seamless integration into battery-powered systems as well as standard 5V and 12V digital circuits. Its CMOS architecture ensures minimal static power dissipation while maintaining fast switching response and accurate logic-level operation.
The device contains four independent XNOR gates, making it ideal for digital comparison, parity checking, equality detection, and logic decision circuits. Its optimized internal structure ensures low thermal generation, high efficiency, and long-term stable performance even under continuous operation conditions. The CD4077 is widely used in both digital and mixed-signal system designs due to its reliability and versatility.
Available in both DIP and SOP package types, it supports flexible integration for prototyping, PCB layout optimization, and scalable production applications.
