After doing some research (meaning searching through a big pile
of databooks), maybe I was deluded about 74HC. However, TI CD74AC logic
is generally specced to 1.5V, maybe that's what I was thinking of.

Not TI SN74AC, that's only specced to 2.0V.

TI parts that start with CD are ex-Harris (and potentially ex-RCA),
am I getting the history right?

Not the holy grail of 0.8V parts in DIP or SOIC though...

Tim.
