Source impedance  28W, V
USB3V3  3.0V).............................................................................................. -1.0V to +4.6V
Total power dissipation (Note 1) ..................................................................................................................................1W
Maximum current out of V

Input clamp current, I
IK (VI < 0 or VI > VDD) ..........................................................................................................±20 mA
Output clamp current, I
OK (VO < 0 or VO > VDD) .................................................................................................. ±20 mA
Maximum output current sunk by any I/O pins........................................................................................................25 mA
Maximum output current sourced by any I/O pins...................................................................................................25 mA
Maximum current sunk byall ports combined.......................................................................................................200 mA

Note 1: Power dissipation is calculated as follows:
Pdis = V
DD x {IDD –  IOH} +  {(VDD – VOH) x IOH} + (VOL x IOL)
2: The original “USB 2.0 Specification” indicated that USB devices should withstand 24-hour short circuits of
D+ or D- to VBUS voltages. This requirement was later removed in an engineering change notice (ECN) sup-
plement to the USB specifications, which supersedes the original specifications. PIC18F97J94 family
devices will typically be able to survive this short circuit test, but it is recommended to adhere to the absolute
maximum specified here to avoid damaging the device.
† 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.
