Note 1: All voltages are measured with respect to the ground pin, unless otherwise specified.  
Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-  
tional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which guar-  
antee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is  
given, however, the typical value is a good indication of device performance.  
Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by T  
, θ , and the ambient temperature T . The maximum

allowable power dissipation is P  
= (T

typical junction-to-ambient thermal resistance is 140˚C/W for package number M08A and is 107˚C/W for package number N08E.  
Note 4: Human body model, 100 pF discharged through a 1.5 kΩ resistor.  
Note 5: Machine Model, 220 pF–240 pF discharged through all pins.  
Note 6: Typicals are measured at 25˚C and represent the parametric norm.  
Note 7: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
