Working Principles

The SN74AHC4066D is based on digital CMOS technology, which allows for high-speed switching and low power consumption. It consists of four independent bilateral switches that can be controlled individually using the control inputs. When a control input is high, the corresponding switch is turned on, allowing the passage of signals between its two terminals. When a control input is low, the switch is turned off, isolating the terminals.
