Absolute Maximum Ratings(N o te 1) Note 1: The “Absolute Maximum Ratings” are those values beyond which

the saf ety of the device cannot be guarante ed. The device s hould not be

operated at these limits. The parametric values defined in the Electrical

Characteristics tables are not guaranteed at the absolute maximum ratings.

The “Re comme nded Operat ing Co ndition s” table will define the cond itions

for actu al device operation.
