Hi
Of course, I think is is interesting that in CMOS, one often uses
analog transmission gates to create XOR functions. Analog transmission
gates are usually used for MUX's.

The AND-OR-INVERT is a very useful function. Think about it--you have not
only a good hunk of a multiplexer, but also most of a XOR gate as well as
a half-adder. It took awhile to get integration up to the point where full
adders (much less ALUs) were available on a single chip.
Cheers,
