Note 1:
2:
Data in “Typical” 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.
3: Negative current is defined as current sourced by the pin.
4: This parameter is characterized, but not tested in manufacturing.
