You can easily tell by the VDD range, power consumption, bandwidth and 1ku price. There is something wrong inside the chip circuitry.

So the trigger DD10 can show a logical “1” or logical “0”. The duration of connection condition datasyeet DD In reply to Fan. There can be a logical level “1” or “0” at the DD Sep 17, 4: The circuit fragment shown above comprises a multiplexer and a Schmitt trigger.

After the address changes the capacitance discharged within several milliseconds to about 2 V. I15 is about 1 ms. This thread has been locked. Please let me know the experiment results and we can go from there. 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.

Due to the holidays, responses may be delayed. CD74HC is mostly used in more digial signal driven use cases where speed, power consumption and price are some key considerations. I can do it some time later.

Sep 21, 4: CD is more industrial or data datassheet applications where leakage current is a key factor while price or power consumption is not quite sensitive.

Mentions Tags More Cancel. If it stops discharging on I1, it has something to do with your pF capacitor. Hi Yourij, It is a good observation. The newly created question will be automatically linked to this question.

I would propose two experiments that might help to isolate the problem.
