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.

Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under

which operation of the device is specified. Operating Ratings do not imply specified performance limits. For specified performance limits

and associated test conditions, see the Electrical Characteristics tables.

(2)

These pins must not exceed VIN.

(3)

The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin. LO, HO and HB are rated at 1kV. 2kV

rating for all pins except VIN which is rated for 1.5kV.
