@lefty, yeah, nothing left, I'm even using the xtal pins. The avr just has a bit part in the circuit but its i/o pins are all spoken for.
@MarkT and tjb: I don't *think* it's a single 555 or monostable because I need one output to go high first when my input goes high and stay high longer when it goes low.
So far I'm looking at the following when the input on the left goes high, the lower right output (/clear) will be slower to go high because of charging its cap thru the 100k rx. when my input drops, the top output will stay high longer because it has to discharge its cap through a 1M vs the 100k. I think this would work but it's a lot of pieces.
