The applications of the ICL7109 are not limited to those
shown here. The purposes of these examples are to pro-
vide a starting point for users to develop useful systems
and to show some of the variety of interfaces and uses of
the combination. In particular the uses of the STATUS,
RUN/HOLD, and MODE signals may be mixed.
The following application notes contain very useful
information on understanding and applying this part and
are available from Intersil Corporation.
