Comment: Exposing the device to stresses above those listed
in the Absolute Maximum Ratings could cause permanent
damage. The device should not be operated under conditions
outside the limits described in the operational sections of this
specification. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
