CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
2. Signals on D+, D-, L, R, D-/L, D+/R, V_BUS, NOx, NCx, COMx, INx, exceeding V_DD or GND by specified amount are clamped. Limit forward
current through clamp to maximum current ratings.
3. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
