* Notice: Stresses above those listed under "Abso-
lute Maximum Ratings" may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions above those indicated in the opera-
tional sections of this specification is not implied. Ex-
posure to absolute maximum rating conditions for
extended periods may affect device reliability.
