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
levels represent normal operating conditions. Higher leakage current can be measured at different input
voltages.
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.
10: These parameters are characterized, but not tested.
