Absolutely. The TV typewriter was a Sept. 1973 article, and it used
7400 series logic (along with some Signetics stuff).
My PDP-8/L, PDP-12 and PDP-11/20 are all chock full of the stuff -
mostly SSI but a little MSI.
My TI TTL Data Book is copyright 1973, and I have not come across much
in the 7400 series TTL that isn't in there.
(On the other hand, the EE lab course on computer design was done using
DTL logic, with the interconnects using re-purposed IBM unit record
machine plugboards).

The hardest
part is finding parts for the FPGA, sure I can use 74XXX
but was it out in 1975-76?
If you mean some specific 74-series part, well, it depends on which
one.
But, if you mean 74-series logic in general, I think so. Sometime
within a year or so of '78, I was working with the stuff, and it was as
an undergrad, so I doubt I would have been working with just-released
logic.
