Working Principles

The TC74HC4066APF is a quad bilateral switch that allows the user to control the flow of analog signals. It consists of four independent switches, each capable of connecting two separate channels. When the control input is high, the switch is closed, allowing the signal to pass through. Conversely, when the control input is low, the switch is open, blocking the signal.
