*NOTICE:
Stresses beyond those listed under
“Absolute Maximum Ratings” may cause
permanent damage to the device. This is
a stress rating only and functional opera-
tion of the device at these or other condi-
tions beyond those indicated in the
operational sections of this specification is
not implied. Exposure to absolute maxi-
mum rating conditions for extended peri-
ods may affect device reliability.
