Absolute Maximum Ratings

Absolute maximums are stress ratings. Exposure of devices to

greater than any of these conditions may adversely affect long-term

reliability. Proper operation under conditions other than those listed

in the Performance/Functional Specifications Table is not implied nor

recommended.

Maximum Ratings Notes

The transient specifications indicate that sample lots were success-

fully tested for 100 mS at the transient stress voltage and were not

damaged. As a practical matter in your application, it is often difficult

to determine how long an input overvoltage was applied. Therefore,

do not exceed the continuous voltage rating.
