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.
