2.1.2 Debounce Switches and Buttons

GUID-A5824919-6D76-4A18-8A15-A80F5AA0453E-low.gifFigure 2-2 Using Logic to Prevent Multiple Triggers of a CMOS Input Due to Switch Bounce
  • Prevents multiple triggers of CMOS inputs due to switch bounce
  • Works when the system controller is asleep
  • Works without a system controller
  • Reduces controller code complexity, no software debounce required
  • See more about this use case in the Logic Minute video Debounce a Switch
  • Find the right Schmitt-trigger buffer through the online parametric search tool
