CD4066 Quad Bilateral Switch IC DIP-14 (CD4066 DIP IC)
The CD4066 is a CMOS quad bilateral switch IC consisting of four independent digitally controlled analog switches. Each switch can pass analog or digital signals in both directions and is controlled by a separate logic level control input making it suitable for signal routing and switching applications.
This IC is widely used in analog signal switching, audio routing, data multiplexing, and signal gating applications where multiple independent bidirectional analog switches are required. It is commonly used in communication circuits, instrumentation, and Arduino projects where controlled switching of analog and digital signals is needed.
