†

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 lev-

els represent normal operating conditions. Higher leakage current may be measured at different input volt-

ages.

3: Negative current is deﬁned as coming out of the pin.

4: The user may choose the better of the two specs.
