These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

Stresses beyond those listed under
absolute maximum ratings
may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other conditions beyond those indicated under
recommended operating
conditions
is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The Human body model (HBM) is a 100-pF capacitor discharged through a 1.5-k
resistor into each pin. The testing is done according
JEDECs EIA/JESD22-A114.
Charged Device Model
Machine Model (MM) is a 200-pF capacitor discharged through a 500-nH inductor with no series resistor into each pin. The testing is
done according JEDECs EIA/JESD22-A115.
