* These parameters are characterized but not tested.
† Data in “Typ” column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance only
and are not tested.
Note 1: In RC oscillator configuration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the
PIC16C9XX be driven with external clock in RC mode.
2: The leakage current on the MCLR
pin is strongly dependent on the applied voltage level. The specified lev-
els represent normal operating conditions. Higher leakage current may be measured at different input volt-
ages.
3: Negative current is defined as current sourced by the pin.
