HELP !!! I have a set of chips (eval samples) that I can't identify -- the
parts are apparently mil-spec  (they look *expensive* :-) and not listed
anywhere I have looked (including IC Master):

24 pin Slim-DIP, ceramic package w/ gold plated pins (brazed). Following
numbers are on the beast:

Topside:        A928
                NCH801DUC
                ES

(I assume the ES means Eval Sample)

Bottom:         D90059E
                901M184B-20


I got curious, and pulled the top cover off one -- the silicon has a logo w/
Pouer written next to it. The geometry of the layout is also bizzare (to
say the least) ...    E-mail would be greatly appreciated .....
