The newly created question will be automatically linked to this question. The circuit fragment shown above comprises a multiplexer and a Schmitt trigger. There can be a logical level “1” or “0” at cx4067 DD The address bus “SET5” switches quickly from 0 to 15 cyclically.

The duration of connection condition between DD I15 is about 1 ms. Any capacitance connected to I After the address changes the capacitance discharged within dattasheet milliseconds to about 2 V. So the trigger DD10 can show a logical “1” or logical “0”.

I don’t see why and how the capacitances discharge so quickly. If you have further questions related to this thread, you may click “Ask a related question” below. In reply to Fan. I can do it some time later. But meanwhile I researched the problem from another side and I found dattasheet the datasheet that the leakage current could be as much as 8 uA.

CD74HC4067: channel off leakage

Go to Support forums. Due to the holidays, responses may be delayed. This thread has been locked. Could somebody explain that fact described above?

Sep 17, 4: Sep 18, 4: I would propose two experiments that might help to isolate the problem. If it stops discharging on I1, it has something to do with your pF capacitor. Otherwise, datasueet other issues. Please let me know the experiment results and we can go from there. Do you have another question?

We are glad that we were able to resolve this issue, and will now proceed to close this thread. Ask a related question Ask a new question. Sep 19, 9: Sep 21, 4: In reply to Yourij Bosco1: Hi Yourij, It is a good observation.

You can easily tell by the VDD range, power consumption, bandwidth and 1ku price. CD74HC is mostly used in more digial signal driven use cases where speed, power consumption and price are some key considerations. CD is more industrial or data acquisition applications where leakage current is a key factor while price or power consumption is not quite sensitive.
