/diy/ - Do It Yourself

I realized that a 74HC74 has a Schmitt trigger clock input. So I came up with this sketch of a switch debounce circuit. A single 74hc74 could de-bounce two buttons/switches.
When the D input is tied to +5V, any clock pulse always sets the flip flop state to 1. Some kind of external circuit (or a micro?) would periodically read the outputs and drive the reset low.
