Ah, a flash of insight. Back then CMOS wasn't 5 volts. More like
anywhere in the range of 5-15 volts. Whereas TTL uses the 2.4 volt
threshold. Looking at the table, the C versions also use about 2/3
the power of the non-C parts. Anybody have the 1980 National Special
Functions databook? Or judging from the part numbers, a old AMD Linear
