A quad bilateral analogue switch IC (M74HC4066B1R) containing four independent SPST switches in a single 14-pin DIP package. Each switch is normally open and closes when a logic-high voltage is applied to its control pin, making it useful for microcontroller-controlled signal routing, audio switching, and multiplexing.
Key Features
- Four SPST Switches – Independently controlled analogue switches
- Low On-Resistance – 80 Ω per switch
- Wide Supply Range – 2–12V operation
- Ultra-Low Power – 8 μA supply current
- DIP-14 Package – Breadboard and through-hole compatible
