It should be very simple and straightforward but it doesn't do what i thought? I have 4 555 in cascade to control a FF but LTSpice simulation go crazy when i connect the 2 outputs to S and R of my flip flop. Am i doing something wrong or spice need some setting i am not aware of?
First 555 create a delay for the 2nd one which is just a 1sec pulse to drive set line in my FF and the bottom 555 is the same, create a delay before sending a pulse to reset the FF.
Why it doesn't work?
