Stresses greater than those listed in the preceding table can cause permanent
damage to the device. This rating is a stress rating only. Functional operation of
the device at any condition above those indicated in the operational sections of
these specifications is not implied. Exposure to absolute maximum rating condi-
tions for an extended period can affect device reliability.
Standard Test Conditions
The characteristics listed below apply for standard test conditions as noted. All
voltages are referenced to GND. Positive current flows into the referenced pin
(see Figure 36).
