The specified levels represent normal operating conditions. Higher leakage current may be measured at different input voltages. 3: Negative current is defined as current sourced by the pin. 4: See “Pin Diagrams” for a list of digital-only and analog pins. 5: VIL source < (VSS – 0.3). Characterized but not tested. 6: Non-5V tolerant pins VIH source > (VDD + 0.3), 5V tolerant pins VIH source > 5.5V. Characterized but not tested. 7: Digital 5V tolerant pins cannot tolerate any “positive” input injection current from input sources > 5.5V. 8: Injection currents > | 0 | can affect the ADC results by approximately 4-6 counts. 9: Any number and/or combination of I/O pins not excluded under IICL or IICH conditions are permitted pro- vided the mathematical “absolute instantaneous” sum of the input injection currents from all pins do not exceed the specified limit. Characterized but not tested. |
