Get with it, guy! Where have you been the last six or so years? Use a
PAL. TTL is obsolete and dead. For high speed, PALs come in D
varieties which run at about 10 nS, and that gives you a trip through
an AND-OR plane. For low cost, the plastic PALs are amazingly cheap.
New PALs provide buried state registers for implementing synchronous
state machines. Programmable polarity outputs mean an end to
DeMorganing equations. There are many new innovations such as UV
erasable, EE erasable, RAM programmed (great for debugging), *large*
arrays, programmable sequencers etc.  All designers should have PALs
as part of their collection of tools.

Note: PAL is a trademark of Monolithic Memories but we make them too.
