Not by a long shot. 74HC is comparable to 74LS. 74AC competes nicely
with 74AS and 74F, however, particularly for driving RAM arrays.
Fairchild had a really nice CMOS line. Unfortunately, National lost
the data book when they bought Fairchild. (ever try to get a 74AC data
book from National?) I just hope they didn't lose anything *important*.
