† 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. Do not drive the PIC16F84A with an
external clock while the device is in RC mode, or chip damage may result.
2: 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 coming out of the pin.
4: The user may choose the better of the two specs.
