Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: IC Supply current specification represents unloaded condition and
does not include external FET gate pull up/down currents (GATE
pins). Actual total IC bias currents will be higher and vary with operating
conditions. See Applications Information.
