Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All current into device pins are positive; all current out of device
pins are negative; all voltages are referenced to ground unless otherwise
specified.

Note 3: An internal clamp limits the GATE pin to a minimum of 10V above
V
a lower GATE pin voltage is desired, use an external zener diode. The GATE
capacitance must be < 0.15 F at maximum V
Note 4: Guaranteed by design and not tested in production.
