Note:
Stresses above those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the de-
vice. This is a stress rating only and functional operation of
the device at any other conditions above those indicated in
the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for ex-
tended periods may affect device reliability.
