Note 1: Data in “Typ” column is at 3.3V, 25°C unless otherwise stated.
2: The leakage current on the MCLR
pin is strongly dependent on the applied voltage level. The specified lev-
els represent normal operating conditions. Higher leakage current can be measured at different input volt-
ages.
3: Negative current is defined as current sourced by the pin.
4: See “Pin Diagrams” for the 5V tolerant I/O pins.
5: V
IL source < (VSS – 0.3). Characterized but not tested.
6: Non-5V tolerant pins V
IH 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 I
ICL 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.
