This parameter applies
to all pins, with the
exception of RB10.
Maximum IICH current
for this exception is
0 mA.

exceptions is 0 mA.

Note 1: Data in “Typical” column is at 3.3V, +25°C unless otherwise stated. Parameters are for design guidance
only and are not tested.
2: V
IL source < (VSS - 0.3). Characterized but not tested.
3: V
IH source > (VDD + 0.3) for non-5V tolerant pins only.
4: Digital 5V tolerant pins do not have an internal high side diode to VDD, and therefore, cannot tolerate any
“positive” input injection current.
5: Injection currents > | 0 | can affect the ADC results by approximately 4 to 6 counts (i.e., V
IH Source > (VDD
+ 0.3) or V
IL source < (VSS - 0.3)).
6: Any number and/or combination of I/O pins not excluded under IICL or IICH conditions are permitted pro-
vided the “absolute instantaneous” sum of the input injection currents from all pins do not exceed the spec-
ified limit. If Note 2, I
ICL = (((Vss - 0.3) - VIL source) / Rs). If Note 3, IICH = ((IICH source - (VDD + 0.3)) / RS).
RS = Resistance between input source voltage and device pin. If (V
SS - 0.3) VSOURCE (VDD + 0.3),
injection current = 0.
