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
