Preliminary
Absolute Maximum Ratings
Comments
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.
