MC14490 Hex Contact Bounce Eliminator IC DIP 16 Package

MC14490 Hex Contact Bounce Eliminator IC DIP 16 Package 

The MC14490 is a hex contact bounce eliminator IC designed to remove unwanted switch bounce effects from mechanical contacts such as push buttons, toggle switches, and keypads. Mechanical switches often produce multiple rapid transitions when actuated; the MC14490 filters these bounces and provides clean, stable digital outputs.

The IC contains six independent debounce channels, each with built-in timing and filtering circuitry. It requires minimal external components and interfaces directly with standard logic circuits. Packaged in a DIP-16 through-hole package, the MC14490 is ideal for prototyping, educational use, and industrial digital input conditioning.
