Note: Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage 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
operational sections of this specification is not implied. Ex-
posure to absolute maximum rating conditions for extended
periods may affect reliability.
