1) Not subject to production test - verified by design/characterization. Hysteresis is implemented to avoid

metastable states and switching due to internal ground bounce. It cannot suppress switching due to external

system noise under all conditions.

2) If the input voltage exceeds the respective supply voltage due to ground bouncing (

IN < VSS) or supply ripple

(

IN > VDDP), a certain amount of current may flow through the protection diodes. This current adds to the

leakage current. An additional error current (

INJ) will flow if an overload current flows through an adjacent pin.

Please refer to the definition of the overload coupling factor

OV.

3) The given values are worst-case values. In production test, this leakage current is only tested at 125 °C; other

values are ensured by correlation. For derating, please refer to the following descriptions: Leakage derating

depending on temperature (

J = junction temperature [°C]): IOZ = 0.05 x e

(1.5 + 0.028 x TJ>) [

μA]. For example, at

a temperature of 95 °C the resulting leakage current is 3.2

μA. Leakage derating depending on voltage level

(DV =

DDP - VPIN [V]): IOZ = IOZtempmax - (1.6 x DV) (μA]. This voltage derating formula is an approximation

which applies for maximum temperature.

4) Drive the indicated minimum current through this pin to change the default pin level driven by the enabled pull

device.

5) Limit the current through this pin to the indicated value so that the enabled pull device can keep the default

pin level.

6) The maximum deliverable output current of a port driver depends on the selected output driver mode. This

specification is not valid for outputs which are switched to open drain mode. In this case the respective output

will float and the voltage is determined by the external circuit.

7) As a rule, with decreasing output current the output levels approach the respective supply level (VOL->VSS,

VOH->VDDP). However, only the levels for nominal output currents are verified.

8) As a rule, with decreasing output current the output levels approach the respective supply level (

OL->VSS,

OH->VDDP). However, only the levels for nominal output currents are verified.
