*Note: 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 devices 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.
