Due to the holidays, responses may be delayed. You can easily tell by the VDD range, power consumption, bandwidth and 1ku price. There can be a logical level “1” or “0” at the DD Ask a related question What is a related question?

Do you have another question? CD74HC is mostly used in more digial signal driven use cases where speed, power consumption and price are some key considerations.

We are glad that we were able to resolve this issue, and will now proceed to close this thread. But meanwhile I researched the problem from another side and I found from the datasheet that the leakage current could be as much as 8 uA.

Could somebody explain that fact described above?

After the address changes the capacitance discharged within several milliseconds to about 2 V. Go to Support forums. CD is more industrial or data acquisition applications where leakage current is a key factor while price or power consumption is not quite sensitive.

Otherwise, it’s other issues. I would propose two experiments that might help to isolate the problem.

Sep 17, 4: If it stops discharging on I1, it has something to do with your pF capacitor. I can do it some time later.
