Note 2:
Voltage spikes below V
SS
at the MCLR pin, inducing currents greater than 80 mA, may cause latch-up. Thus,
a series resistor of 50 to 100
should be used when applying a “l(fā)ow” level to the MCLR pin rather than pull-
ing this pin directly to V

ELECTRICAL CHARACTERISTICS - PIC16C54/55/56/57
NOTICE: Stresses above those listed under “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.
