Note 1:

Data in “Typ” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only

and are not tested.

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.

Negative current is defined as current sourced by the pin.

Refer to Table 1-4 for I/O pins buffer types.

VIH requirements are met when internal pull-ups are enabled.
