Can someone explain to me how to use a schmitt trigger to debounce a circuit. Also does anyone know the pin outs to the 4518B as i am making a decade counter using a seven segment display.

Russ, an RC filter is generally followed by a Schmitt trigger to give a fast risetime, as you undoubtedly know. What configuration do you have in mind?

contact debouncing

Thought I would my 2 cents worth. The reason that debouncing is necessary is that the mechanical contacts generally vibrate and cause more than just one closure or one brake of the circuit. The RC components and the one-shot MV eliminate the multiple mechanical bounces of the contacts, that most electronic circuits would normally respond to.
