Notes:

1. V_ILmin and V_IHmax are reference values only and are not tested.

2. This parameter is characterized initially and after a design or process change that affects the parameter. Not 100% tested.

3. The total current sunk by all I/Os must be limited to 100 mA and each I/O limited to 25 mA maximum.

4. The total current sourced by all I/Os must be limited to 85 mA.
