Otherwise, it’s other issues. Sep 19, 9: In reply to Yourij Bosco CD is more industrial or data acquisition applications where leakage current is a key factor while price or eatasheet consumption is not quite sensitive.
There can be a logical level “1” or “0” at the DD Do you have another question? Due to the holidays, responses may be delayed. You can easily tell by the VDD range, power consumption, bandwidth and 1ku price. Menu Search through millions of questions and answers User.

I can do it some time later. Hi Yourij, It is a good observation.
CD74HC4067: channel off leakage
Ask a new question Ask a new question Cancel. Any capacitance connected to I Could somebody explain that fact described above?
Please let me know the experiment results and we can go from there. Sep 18, 4: All content and materials on this site are provided “as is”. In reply to Yourij Bosco1: The circuit fragment shown above comprises a multiplexer and a Schmitt trigger. CD74HC is mostly used in more digial signal driven use cases where speed, power consumption and price are some key considerations.

But meanwhile I researched the problem from another side and I found from the datasheeh that the leakage current could be as much as 8 uA. Go to Support forums. Mentions Tags More Cancel.
I would propose two experiments that might help to isolate the problem. I don’t see why and how the capacitances discharge so quickly.
