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........................................................................................................................100 mA

Maximum current sourced by PORTA................................................................................................................... 100 mA

Maximum current sunk by

PORTB........................................................................................................................100 mA

Maximum current sourced by PORTB .................................................................................................................. 100 mA

Note 1: Power dissipation is calculated as follows: Pdis = VDD x {IDD –

 IOH} +  {(VDD – VOH) x IOH} + (VOL x IOL)

2: Voltage spikes at the MCLR pin may cause latch-up. A series resistor of greater than 1 k

 should be used

to pull MCLR to VDD, rather than tying the pin directly to VDD.

† 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.
