Sep 17, 4: Hi Yourij, It is a good observation.

You can easily tell by the VDD range, power consumption, bandwidth and 1ku price. Please let me know the experiment results and we can go from there.

This fact explains the behavior of the circuit. Sep 18, 4: TI is a global semiconductor design and manufacturing company. In reply to Yourij Bosco Ask a related question Ask a new question. There is something wrong inside the chip circuitry. We are glad that we were able to resolve this issue, and will now proceed to close this thread.


Otherwise, it’s other issues.

CD74HC is mostly used in more digial signal driven use cases where speed, power consumption and price are some key considerations.

Any capacitance connected to I I would propose two experiments that might help to isolate the problem. The duration of connection condition between DD I15 is about 1 ms.

I don’t see why and how the capacitances discharge so quickly.

This thread has been dahasheet. 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.


CD is more industrial or data acquisition applications where leakage current is a key factor while price or power consumption is not quite sensitive.
