Experiment 6 - The 2-bit Magnitude-Comparator II

In the last experiment, you have seen that a 2-bit magnitude comparator is quite complicated to build with only logic gates. Fortunately, there exist integrated circuits, which already contain a digital comparator...

The C-MOS 4063 contains a pre-programmed 4-bit magnitude comparator. You can easily use it as a 2-bit magnitude comparator...

Circuit diagram of a 2-bit magnitude comparator with the C-MOS 4063.

With the circuit shown you build the 2-bit magnitude comparator. Make sure you connect all unused inputs as shown! More on that later...

Circuit of a 2-bit magnitude comparator with the C-MOS 4063. (Enlarge)

In the next experiment you look at the complete 4-bit magnitude comparator of the C-MOS 4063...
