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. Roman Dnia 7 lipca 2018 02:16 David G Dixon < dixon at mail.ubc.ca > napisał(a): Hey Team, So, just a quick update on the fifth generator situation... (...) 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?
