Ask a new question Ask a new question Cancel. 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. CD74HC is mostly used in more digial signal driven use cases where speed, power consumption and price are some key considerations. Sep 19, 9: Ask a related question What is a related question?

TI is a global semiconductor design and manufacturing company. The address bus “SET5” switches quickly from 0 to 15 cyclically. Mentions Tags More Cancel.

CD is more industrial or data acquisition applications where leakage current is a key factor while price or power consumption is not quite sensitive. Do you have another question? I would propose two experiments that might help to isolate the problem. Due to the holidays, responses may be delayed.

I don’t see why and how the capacitances discharge so quickly. The duration of connection condition between DD You can easily tell by the VDD range, power consumption, bandwidth and 1ku price. After the address changes the capacitance discharged within several milliseconds to about 2 V. If you have further questions related to this thread, you may click “Ask a related question” below.
