In addition to that, there are 2 sets of digits on the IC.  One of
them (4 digits) is the date-code and is usually on top.  You can tell
that it is the date-code as it has something like 9123 which translate
to 1991 workweek 23.

Just look at the other code (which usually have 1 or 2 alphabets) for
your speed rating.
