The CD4066 is a high-performance quad bilateral switch IC from the CD4XXX CMOS logic family, designed for efficient analog and digital signal switching 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 signal routing in a wide range of applications.
Operating over a wide supply voltage range of 3V to 15V, the CD4066 offers excellent design flexibility compared to lower-voltage logic families. This broad voltage compatibility allows seamless integration into battery-powered systems as well as standard 5V and 12V electronic circuits. Its CMOS architecture ensures minimal static power dissipation while maintaining low ON resistance for accurate and distortion-free signal transmission.
The device includes four independent bilateral switches that can pass both analog and digital signals in either direction. This makes it ideal for signal gating, multiplexing, and switching applications where low leakage and high linearity are required. Its optimized internal structure ensures low thermal generation, high efficiency, and long-term stable operation even under continuous use conditions.
Available in both DIP and SOP package types, the CD4066 supports flexible integration for prototyping, PCB layout optimization, and scalable production environments.
