A small part of the 4000 series is shown in Figure 11.2.

series of TTL digital integrated circuits
Once we have a family (well, two families actually) of digital
integrated circuits that contain logic gates, it’s fairly obvious
that building more complex digital circuits becomes easier. It
is merely a matter of using the gates within these integrated
circuits to build more complex circuits. On the other hand,
further devices in both ranges of integrated circuits are
themselves more complex, containing circuits built from the
gates themselves.
