AC Parameters
The following conditions apply to all the following parameters, unless otherwise specified.
AC: +5V ≤ V
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by T
junction to ambient thermal resistance), and T
or the number given in the Absolute Maximum Ratings, whichever is lower.
Note 3: Human body model, 1.5KΩ in series with 100pF.
Note 4: Guaranteed by tests at V
Note 5: Guaranteed parameter, not tested.
Note 6: No protection against excessive pin 7 current is necessary providing the package dissipation rating will not be exceeded.
Note 7: This will determine the maximum value of R
