The data sheet is in the 1976 Signetics Data Manual. I scanned the first
page (the second is signal timing diagrams):
http://www.jkearney.com/Misc/82s21-p1.pdf (255KB). Let me know if you want
the second page.
The book is hard-bound and I didn't have time to crop it, so it isn't a
great scan, sorry.
