Absolute maximum ratings
Stresses above those listed as 'absolute maximum ratings' may cause permanent damage
to the device. This is a stress rating only and functional operation of the device under these
conditions is not implied. Exposure to maximum rating conditions for extended periods may
affect the device reliability.

When several inputs are submitted to a current injection, the maximum

is the absolute sum of the
positive and negative injected currents (instantaneous values). These results are based on characterization
with

maximum current injection on four I/O port pins of the device.
