Thanks a lot man, you've really been helping me out with my IC logic search. One last thing, on the simple diagram what is capacitor and resistor in the input, I mean what is the resistance of the resistor and what is the capacitance of the capacitor that you have in the simple drawing? Could you draw the ICs as they would be put on the circuit instead of the simple drawing that you posted in an earlier post? I want to get that circuit finished drawing, so I can start testing the circuit before I start soldering the board together.
