1.0 ABSOLUTE MAXIMUM RATINGS
The ABSOLUTE MAXIMUM ratings below are stress ratings only. Operation at or beyond these maximum ratings can cause
permanent damage to device. Electrical specifications do not apply when operating beyond rated operating conditions. All
voltages are specified relative to SG unless otherwise noted. Positive pin current represents current flowing out of the pin.
