Specifications

Note :
1. Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. This a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification are not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. Preliminary, subject to change.
