1. “Max” means the highest value where the pin is guaranteed to be read as low.
2. “Min” means the lowest value where the pin is guaranteed to be read as high.

sient), the following must be observed:
- The sum of all IOL should not exceed 20mA
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test condition.
transient), the following must be observed:
- The sum of all IOH should not exceed 2mA
This restriction is put because the device should be within spec throughout the whole operation range. The integrated volt-
age regulator could have problems providing this output when supplying high currents at low VFET voltages.
