Electrical Specification
*NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the oper-
ational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
