Input clamp current, IIK (VI < 0 or VI > VDD)............................................................................................................... 20 mA
Output clamp current, IOK (Vo < 0 or Vo >VDD)......................................................................................................... 20 mA
Maximum output current sunk by any I/O pin....................................................................................................25 mA
Maximum output current sourced by any I/O pin .............................................................................................. 25 mA
Maximum current sunk by PORTA, PORTB and PORTC (combined)............................................................ 200 mA

Note 1: Power dissipation is calculated as follows: PDIS = VDD x {IDD - ∑ IOH} + ∑ {(VDD - VOH) x IOH} + ∑(VOL x IOL).
† 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:
Voltage spikes below VSS at the MCLR pin, inducing currents greater than 80 mA, may cause latch-up.
Thus, a series resistor of 50-100 Ω should be used when applying a “low” level to the MCLR pin, rather than
pulling this pin directly to VSS.
