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 condi-
tions above those indicated in the operational sections
of this specification is not implied. Exposure to abso-
lute maximum rating conditions for extended periods
may affect reliability.
