Note 1: VUSB must always be

 VDD +0.3V.

2: Power dissipation is calculated as follows: PDIS =VDD x{IDD –

 IOH} +  {(VDD –

VOH)x IOH}+

(VOL xIOL).

† 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 above maximum rating conditions for

extended periods may affect device reliability.
