All power (V

) and ground (V

, V

, V

) pins must always be
connected to the external power supply

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

while a negative injection is induced
by V

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

maximum must always be respected
