Standard low power TTL, yes. However, very obscure part; single J-K

looking for it.

You may have more luck with the straight SN7472N part. I doubt that
it will affect the operation of the circuit; you should check it out
to be sure.
Suggestion: If the original chip is socketed, it would probably be pretty easy to construct an adapter to allow the use of a more modern replacement, such as a 74L or LS76.
