Note 1. Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2.
All currents into pins are positive; all voltages are referenced to
GND unless otherwise noted.
Note 3. These pins can be tied to voltages below –0.3V through a resistor
that limits the current below 1mA.
Note 4. The GATE pin is referenced to V
