Hi every body.
dears I want to make a circuit that its input is TTL and its output alternate between zero and 24V. I make one but it doesn't work properly .
I attached it and its wave form. green wave is for V1 and blue is output(Q3's voltage ).
please analyze it and let me know my mistake. I start to change the circuit but I like know why this circuit doesn't work. because I reach to desire wave form in simulation with orcad.
and if you have better idea let me be aware your idea.
