Note 1: “Absolute Maximum Ratings” are those values beyond which the

safety of the device cannot be guaranteed. Except for “Operating Tempera-

ture Range” they are not meant to imply that the devices should be oper-

ated at these limits. The Electrical Characteristics table provides conditions

for actual device operation.
