5 Electrical Characteristics
5.1 Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause per-
manent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated under
“Electrical Requirements” is not implied. Exposure to absolute-maximum-rated con-
ditions for extended periods may affect device reliability.
