Note 1: Power dissipation is calculated as follows:
Pdis = V
DD x {IDD –  IOH} +  {(VDD – VOH) x IOH} + (VOL x IOL)
2: Voltage spikes below V
SS 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 V
SS.
3: V
USB3V3 must always be VDD + 0.3V. VUSB3V3 must also be maintained VDD - 0.3V on PIC18LF2X/45K50
devices.
† 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.
