Creating a finite state machine with circuitikz

Dear TEX Community,

I want to create a state machine using Curcuitikz (not a state diagram), however I don’t know how to go about it. Unfortunately, I can’t find flip-flop like boxes which have more than three pins on the long side. Attached is a screenshot of the circuit to be created.

I apologize if this post seems a bit rushed and ungrateful, however I just started using LaTeX for studying. If you could give me a hint already, I can see if I can get ahead on my own.

Thank you a lot!

EDIT:
As I have not clue on how to do this, I can just give you the document header which already worked with drwaing another electrical schematic.
