In reply to Yourij Bosco Could somebody explain that fact described above? In reply to Yourij Bosco1: The circuit fragment shown above comprises a multiplexer and a Schmitt trigger. Go to Support forums. This thread has been locked. Menu Search through iv of questions and answers User.

There is something wrong inside the chip circuitry. Sep 19, 9: Please let me know the experiment results and we can go from there. Content on this site may contain or be subject to cc4067 guidelines or limitations on use.

After the address changes the capacitance discharged within several milliseconds to about 2 V.

The newly created question will be automatically linked to this question. The duration of connection condition between DD I15 is about 1 ms. In reply to Fan.

CD74HC4067: channel off leakage

But meanwhile I researched the problem from another side dataasheet I found from the datasheet that the leakage current could be as much as 8 uA.

If you have a related question, please click the ” Ask a related question ” button in the top right corner. If it stops discharging on I1, it has something to do with your pF capacitor. I can do it some time later. This fact explains the behavior of the circuit.


Otherwise, it’s other issues. I don’t see why and how the capacitances discharge so quickly. CD74HC is mostly used in more digial signal driven use cases where speed, power consumption and price are some key considerations.

I would propose two experiments that might help to isolate the problem. You can easily tell by the VDD range, power consumption, bandwidth and 1ku price. TI is a global semiconductor design and manufacturing company.

We are glad that we were able to resolve this issue, and will now proceed to close this thread.
