Functional Features

• CD4066BCN allows bidirectional switching of analog or digital signals.
• It provides a low on-state resistance, enabling efficient signal transmission.
• The control inputs allow for easy selection of the desired switch.

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered devices.
• Wide operating voltage range allows for compatibility with various systems.
• High noise immunity ensures reliable signal switching.
• Fast switching speed enables quick response in time-critical applications.

Disadvantages
