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 may be measured at different input 
voltages.

3: Negative current is defined as current sourced by the pin.
4: See “

” for a list of digital-only and analog pins.

7: Digital 5V tolerant pins cannot tolerate any “positive” input injection current from input sources > 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 I

 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.
