Never allow a stress to exceed the values listed
under "Absolute Maximum Ratings", otherwise the
device would suffer from a permanent damage. Nor
is a stress at the listed value be allowed to persist
over a period, since an extended exposure to the
absolute maximum rating condition may also affect
the reliability of the device, if not causing a damage
thereof.
