†

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.
