Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters
are absolute voltages referenced to V
SS
; all currents are defined positive into any lead. The Thermal Resistance and Power
Dissipation ratings are measured under board mounted and still air conditions.

Recommended Operating Conditions
For proper operation the device should be used within the recommended conditions. All voltage parameters are absolute
voltages referenced to
V
SS
. The
V
