Single transition mode to Gnd Pin Please provide a schematic of what you have beside a schematic of the circuit in the datasheet.
To participate you need to register. RS k Pin 4. I was expecting nothing on the output except maybe momentarily ,until I had started the count and it had completed.
Not Connected Pin 5. Just saying hello Started by MichaelaJoy Yesterday at 6: I think I am reading the logic and timing tables correctly and that the k, k and 50 pic is all in range? Articles Top Articles Search resources. Welcome to our site!

Hi dr pepper, I see what you mean mate but just tried and still same results. What is my problem here? CT 50pF Pin 3. Hi to all, I am trying to build a long interval timer using the HCF IC and am not getting the results I expected, but I am not certain that I am reading the datasheet correctly. Then you will see what is wired wrong.
Potentiometer Questions Started by norbss Yesterday at The datasheet is puzzling me to say the least. RTC k Pin 2.
