Max. output current sourced by a single I/O port (PORTA, B or C) ..................................................................40 mA
Max. output current sunk by a single I/O port (PORTA, B or C)........................................................................50 mA
Note 1: 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 “low” level to the MCLR
pin rather
than pulling this pin directly to V
SS.
2: Power Dissipation is calculated as follows: Pdis = V
DD x {IDD –  IOH} +  {(VDD – VOH) x IOH} + (VOL x IOL)
† 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.
