Functional Features

• Quad bilateral switch with independent control of each switch
• Low power consumption
• High-speed operation
• Wide operating voltage range
• Break-before-make switching action

Advantages and Disadvantages

Advantages: - Independent control of each switch allows flexible signal routing. - Low power consumption makes it suitable for battery-powered devices. - High-speed operation enables efficient data transmission. - Wide operating voltage range provides compatibility with various systems. - Break-before-make switching action prevents short circuits.

Disadvantages: - Limited number of switches (4) in a single package. - Not suitable for high-power applications.

Working Principles

The CD74HC7266MT consists of four independent bilateral switches. Each switch has two control inputs, A and B, and two signal paths, Y and B. When the control inputs are activated, the corresponding switch connects the Y and B paths, allowing the signal to pass through. The break-before-make switching action ensures that there is no momentary short circuit during switching.
