Digital integrated circuits IIIn 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.
