*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.
Note 1:
Power dissipation is calculated as follows: Pdis=V
DD
x {I
