yes - that's where i got the idea they were CMOS
The original, standard
74 series (7400, 7401, etc.) as well as the 74
F, H, L, S, AS, LS, and
ALS variants are bipolar TTL. The 54xx are the same gates, however, they are the military temperature range and 64xx are industrial temperature range variants.
LS was probably the most commonly used (low-power, Schottky) in most places in most circuits, at least through into the early 1990s for most circuits, though often still with a smattering of plain 74 due to the increased current output capability, thus greater fanout. 74F (fast) was commonly used once speeds (especially glue logic on later computer motherboards, etc.) went up above the 16 MHz or so that most of the parts in the earlier series could handle.
I remember doing lots of circuit designs as a kid where an LS couldn't quite drive all the gates you needed, so you'd grab a regular 74 version from the drawer of salvaged chips and swap it in place of the LS. LS was nice because when you had dozens and dozens of chips in your design, you could still run from a 7805 regulator.
Rows and rows of regular 74 made for a power hungry beast!
