or any other conditions greater than those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

powered according to the operating conditions table. If VDDUSB supply
voltage does not meet the specification in the operating conditions table, these
pins could suffer long term damage when driven to +5V. If this condition is
seen in the application, it can be corrected with additional circuitry to use the
external host to power only the V
detail and reliability information.
PG15-11, PH6, AND PH7 is +5.5V.
