There is something wrong inside the chip circuitry. In reply to Yourij Bosco No license, either express or implied, by estoppel or otherwise, is granted by TI.

If it stops discharging on I1, it has something to do with your pF capacitor.

Sep 19, 9: I would propose two experiments that might help to isolate the problem. CD74HC is mostly used in more digial signal driven use cases where speed, power consumption and price are some key considerations.


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

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

Otherwise, it’s other issues. You can easily tell by the VDD range, power consumption, bandwidth and 1ku price. I don’t see why cd406 how the capacitances discharge so quickly. I15 is about 1 ms.
