Note 2:
Voltage spikes below Vss at the MCLR pin, inducing currents greater than 80 mA may cause latch-up. Thus,
a series resistor of 50 to 100W should be used when applying a low level to the MCLR pin rather than pulling
this pin directly to Vss.
ELECTRICAL CHARACTERISTICS - PIC12C5XX
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.
