*Stresses greater than those listed under "Absolute
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. Exposure
to absolute maximum rating conditions for extended
periods
may
affect
reliability.
