† NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above
those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions
for extended periods may affect device reliability.

Note 1: Voltage spikes below V
Note 2: Power dissipation is calculated as follows: Pdis = V
ELECTRICAL CHARACTERISTICS FOR PIC16F84A
a series resistor of 50-100 should be used when applying a “low” level to the MCLR pin rather than pulling
this pin directly to V
