I know how to build this circuit with MOSFET using CMOS technology but it requires 18 MOSFET. I would like to know how can I build the same circuit using an integrated circuit in order to reduce its size:
I looked at some catalogs of electronics components and I didn't find any integrated circuit that embeds these four gates in one chip.
Does this kind of integrated circuit exists? If yes, how can I easily find them? If no, how can I reduce the size of my circuit?
