=================
off the top of my head, the 74xx should be more robust than the 40xx,
especially when interfacing to other stuff. IIRC, it should handle higher
output current and be more resilient to ESD.

"Implicit in the term "national defense" is the notion of
defending those values and ideals which set this Nation
apart. For almost two centuries, our country has taken
singular pride in the democratic ideals enshrined in its
Constitution, and the most cherished of those ideals have
found expression in the First Amendment. It would indeed
be ironic if, in the name of national defense, we would
sanction the subversion of one of those liberties...
which makes the defense of the Nation worthwhile."
