Sep 18, 4: If it stops discharging on I1, it has something to do with your pF capacitor. Due to the holidays, responses may be delayed. I can do it some time later. 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.

So the trigger DD10 can show a logical “1” or logical “0”. After the address changes the capacitance discharged within several milliseconds to about 2 Fatasheet. Hi Yourij, It is a good observation.

This fact explains the behavior of the circuit. I don’t see why and how the capacitances discharge so quickly. Ask a new question Ask a new question Cancel.

Any capacitance connected to I I15 is about 1 ms.

Do you have another question? The address bus “SET5” switches quickly from 0 to 15 cyclically.
