I was also looking for a single multiplexer instead of quad one and found a couple of them constructed from simple gates, including this one. I'll check. Two pins less but probably at a price of more routing area needed. Need to check and see what pays better off. > > Hmmm. Why not just a PAL16V8 programmed to your heart's desire? ;-) Not everyone can program a PAL and I prefer normal TTL were possible since it allows everyone to rebuild the circuit, even in a few years when PALs or GALs might not be easily available anymore or programmers are hard to come by. Reminds me of the people who, upon seeing the ZX spectrum rebuild with standard TTL, asked 'Why not use a CPLD?'. They really missed the point of the whole project. Sometimes you have to use programmable logic since the circuit would become too large otherwise. But a handfull of standard TTLs does not qualify as 'too large'.
