Absolute Maximum Ratings(Note 2) Recommended Operating
Conditions
Note 2: Absolute maximum ratings are values beyond which the device
may be damaged or have its useful life impaired. Functional operation
under these conditions is not implied.
Note 3: In this case the output of the register is clocked to the inputs and
the overall Q output is unchanged at Q
n
.
Note 4: Either voltage limit or current limit is sufficient to protect inputs.
