There still remains the problem of dealing with active low inputs to a MUX. The rules
are simply stated:
For Active Low Data Select Inputs to MUXs
(1) Complement the MUX K-map axis of any active low data select input and
renumber the K-map cells. The new cell numbers identify the MUX inputs to which
they must be connected.
