Pin input voltage
The input voltage measurement on a pin of the device is described in Figure 11.

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 device reliability.

All power (VDD1, VDD2, VDDA) and ground (VSS1, VSS2, VSSA) pins must always be connected to the
external power supply.

Positive injection is not possible on these I/Os. VIN maximum must always be respected. IINJ(PIN) must
never be exceeded. A negative injection is induced by VIN<VSS.

IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum
cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive
injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS.
