TheCD4066is aQuad Bilateral Switch IC, that is, it has four switches which can be controlled individual using a control pin. These switches can conduct in both the directions making it bilateral, it is commonly used for multiplexing analog or digital signals.The switches have very low internal resistance making it suitable for audio applications.
