DC Electrical Characteristics
(Continued)
Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2:
Operating Ratings indicate conditions for which the device is intended to be functional. These ratings do not guarantee specific performance limits,
however. 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 3:
All voltages are measured with respect to GND unless otherwise specified.
Note 4:
See AN450 ‘‘Surface Mounting Methods and Their Effect on Product Reliability’’ or the section titled ‘‘Surface Mount’’ found in any current Linear Data
Book for other methods of soldering surface mount devices.
Note 5:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
,
H

. The maximum
allowable power dissipation at any temperature is P

Note 8:
Tested Limits are guaranteed and 100% tested.
Note 9:
Design Limits are guaranteed, but not 100% tested.
Note 10:
When the input voltage (V

) at any pin exceeds the power supplies (V

), the current at that pin should be limited to 5 mA. The 20 mA
maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 5 mA to four.
