Hello.
I need to know the logical digital output thresholds of the S32K1xx series, based on the current supplied for the range of VDD = 3.3V.
Already consulted the Table 17- Datasheet (S32K-DS) but they are only specified for certain currents (3mA-3.5mA to VDD = 3.3V) , as well as the Figure 8 - AN2434 that only specifies it for VDD = 5V.

Specified Voh/Vol is min/max value when sourcing/sinking current is Ioh/Iol as specified.
V-I characteristic for logic 1 (output) can estimated by linear approximation between points and <Ioh;Voh> and <0mA ; VDD>. The same way you can estimate V-I characteristic for logic 0.

How it is defined (i.e. minimum current at defined voltage) it is basically worst case.
You can also use IBIS model we are providing.
