† Notice: Stresses above those listed under “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 operational listings of this specification

is not implied. Exposure to maximum rating conditions

for extended periods may affect device reliability.
