Absolute maximum ratings10.2
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 device reliability.

All power (V

) and ground (V

I
INJ(PIN)
must never be exceeded. This is implicitly insured if V
IN
maximum is respected. If V
IN
maximum
cannot be respected, the injection current must be limited externally to the I
INJ(PIN)
value. A positive
injection is induced by V

. For true open-drain
pads, there is no positive injection current, and the corresponding V

maximum must always be respected
