ELECTRICAL CHARACTERISTICS

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The GATE pin is internally limited to a minimum of 11.5V. Driving

this pin to voltages beyond the clamp may damage the part.

Note 3: All currents into the device pins are positive; all currents out of

device pins are negative. All voltages are referenced to ground unless

otherwise specified.
