It is desirable to connect the gates together in as few a number as possible to create a desired output result given a fixed set of input conditions. Alternatively it may be necessary to utilize one type of gate to produce several other logic functions. Purchasing one IC type in bulk quantity has the advantage of reducing the cost of these chips. Two theories are used here. 1) Boolean Algebra. 2) De-morgans Theorem.
