Notes

ESD testing is performed in accordance with the Human Body Model (HBM) (CZAP = 100 pF, RZAP = 1500 ), and the Charge Device

Model (CDM), Robotic (CZAP = 4.0 pF).

Need external ESD protection diode array to meet IEC1000-4-2 15000 V Air Gap discharge requirement. (CZAP= 150 pF,

RZAP=330 ohm).

Table 5. Thermal Ratings

All voltages are with respect to ground unless otherwise noted. Exceeding these ratings may cause a malfunction or permanent

damage to the device.
