Digital integrated circuits II
11 Digital integrated circuits II
In the last chapter we saw how electronic logic gates can be
constructed from other electronic logic gates, however, as
far as the hobbyist or the person starting out in electronics
is concerned, knowing that logic gates can be created this
way is one thing. No-one in their right mind would actually
go about creating anything other than the simplest of logic
gates like that, because it’s just too time-consuming and too
expensive. ICs represent the only sensible option.
Now we’re going to take a look at some IC logic gates, in
the form of the same sort of ICs we’ve already studied and
experimented with. The ICs shown over the next few pages
represent only the tip of the digital IC iceberg though, as I’ve
only shown some of the most common and simplest. The digital
circuits we’ll look at later in this chapter are all available
in one IC form or another as well, so the list of available ICs
is very long indeed — not just the few shown here.
