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.

INJ(TOT)

(3)(4)(5)

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

IINJ(PIN)

is the absolute sum of the

positive and negative injected currents (instantaneous values). These results are based on characterization

with

IINJ(PIN)

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

Sum of injected currents
