All I'm saying is these days the "7400 series" refers by default to the pinouts, not the
original TTL logic family (which has been obsolete for decades, firstly in favour of
"LS" and "ALS" and "F" TTL variants, and then CMOS).
New designs don't use TTL chips (with family codes "", "S", "LS", "F", "ALS" etc),
because they are out-performed comprehensively by CMOS families on all fronts
(well, perhaps there are a few special cases, but in general).
"HC", "HCT", "AC", "LVC" etc are the families of choice, so when someone talks of
a 7414 hex inverter they would typically mean a 74HC14, and quite rightly.
If you want to refer to an original TTL chip you should quote the whole part number
as in SN7414D (incidentally they are hard to find and expensive too!)
