Absolute Maximum Ratings(Note 1)
Note 1: The “Abs olute Maxim um Ratings ” are those valu es beyond w hich
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 no t 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.
