• 2: PIC18(L)F4XK22 devices.
• 3: Function default pin.
• 4: Function default pin (28-pin devices).
• 5: Function default pin (40/44-pin devices).
• 6: Function alternate pin.
• 7: Function alternate pin (28-pin devices).
• 8: Function alternate pin (40/44-pin devices)

• Note 1: Power dissipation is calculated as follows: Pdis = VDD x {IDD - IOH} + {(VDD - VOH) x IOH} + (VOL x IOL)
• 2: Voltage spikes below VSS at the MCLR/VPP/RE3 pin, inducing currents greater than 80 mA, may cause latch-up. Thus, a series resistor of 50-100 should be used when applying a 'low' level to the MCLR/VPP/ RE3 pin, rather than pulling this pin directly to VSS.

† 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.
