Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. For guaranteed specifications and test conditions, see the  
Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed.  
Note 2: For operation in ambient temperatures above 25˚C, the device must be derated based on a 150˚C maximum junction temperature and a package thermal  
resistance of 110˚C/W, junction to ambient.  
Note 3: ESD susceptibility test uses the “human body model, 100 pF discharged through a 1.5 kresistor”.  
Note 4: Typicals are at T = 25˚C and represent the most likely parametric norm.

Note 5: Relative difference between the input clamp voltage and the minimum input voltage which produces a horizontal output pulse.
