Absolute Maximum Ratings(Note 1)
Note 1: T he “Absol ute Maximum Ratings” are those values be yond 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 gua rant eed at the absolute maximum rati n gs.
The “Re comme nded Operat ing Co ndition s” table will define the cond itions
for actu al device operation.
