These parameters are characterized but not tested.

†

Data in “Typ” column is at 5.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are

not tested.

Note

Negative current is defined as current sourced by the pin.

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.

This specification applies to all weak pull-up pins, including the weak pull-up found on RA3/MCLR. When RA3/MCLR is

configured as MCLR Reset pin, the weak pull-up is always enabled.
