Working Principles

The CD74HCT4066MT is a quad bilateral switch that allows the user to control the flow of analog signals. It consists of four independent switches, each controlled by its own control input. When the control input is high, the corresponding switch is closed, allowing the signal to pass through. Conversely, when the control input is low, the switch is open, blocking the signal.

The CD74HCT4066MT utilizes CMOS technology, which provides high-speed switching capabilities while consuming minimal power. The break-before-make switching action ensures that there is no momentary short-circuit during the switching process, enhancing the reliability of the device.
