I'd say even up to 100k and nothing else.  But you also said it doesn't work in another circuit with clean 0/5V clock, so that probably wouldn't help.  Does it have to be 4024? So many other choices for one divider section.

So, I'm thinking that it would have been OK just to put the 10k  current-limiting resistor in between the raw square wave output and the 4024  CLK input, and let the on-board protection diode limit the voltage, with a  paltry 500uA of current flowing through it, which isn't going to hurt  anything.  Am I thinking about this correctly, or is it just a whole lot  harder and more sophisticated than my tiny brain is capable of conceiving?
