Many physical switches can bounce for hundreds of microseconds after being pressed, while most logic devices respond in just a few nanoseconds. This can result in false triggers and erroneous output. By adding an appropriate debounce circuit between a button and a CMOS input, these bounces can be eliminated.


See more about this use case in the Logic Minute video Debounce a Switch.
