Absolute maximum ratings
Absolute maximum ratings are limiting values of permitted operation and should never be exceeded under the worst
possible conditions either initially or consequently. If exceeded by even the smallest amount, instantaneous
catastrophic failure can occur. And even if the device continues to operate satisfactorily, its life may be considerably
shortened.
