VIL min and VIH max are reference values only and are not tested. 5. This parameter is characterized initially and after a design or process change that affects the parameter. Not 100% tested. 6. The total current sunk by all I/Os must be limited to 100 mA and each I/O limited to 25 mA maximum. 7. The total current sourced by all I/Os must be limited to 85 mA. |
