ELECTRICAL CHARACTERISTICS
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.
Pdis = V
Thus, a series resistor of 50-100 should be used when applying a “low” level to the MCLR/V
than pulling this pin directly to V
