There are earlier ones. As you might know, the SN74xx

the SN740, SN741 etc. (only three digits!). After TI expanded this family
they went over to four digit part numbers and just appended a zero to the
already available parts. Thus the SN740 became the SN7400, the SN741 the
SN7410 and so on. I have a TI databook somewhere that has the old part
numbers.
That's the first I've ever heard that one, which explains the somewhat
puzzling number sequences, and how they got that way...
