(NOTE) 1.
Str_
above those lilted under "ABSOLUTE MAXIMUM RATINGS" may cause permanent damage
to
the
device. Normal opera-
tion should be limited
to
those conditions specified under "ELECTRICAL CHARACTERISTICS -1" and
"·2".
The use beyond these
conditions may cause LSI's malfunction
and
at
the
same time affects devica reliability.
