I am looking for a datasheet for the N8202N or
equivalent.
It would have been described in "Digital 8000 series TTL/MSl".
It was apparently manufactured by Signetics and equivalents seem to have
been available from Motorola and others.

Datasheetarchive.com is sometimes your friend. In this case, only a
specsheet, hope that helps
