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
1: In RC oscillator configuration, the OSC1 pin is a Schmitt Trigger input. It is not recommended that the PIC16C55X be
driven with external clock in RC mode.
2: The leakage current on the MCLR pin is strongly dependent on applied voltage level. The specified levels represent nor-
mal operating conditions. Higher leakage current may be measured at different input voltages.
3: Negative current is defined as coming out of the pin.
