Output Loading  
The output stage of the mux-amp is very power-  
ful, and can source 80 mA and sink 120 mA. Of  
course, this is too much current to sustain and  
the part will eventually be destroyed by excessive  
dissipation or by metal traces on the die opening.  
The metal traces are completely reliable while de-  
livering the 30 mA continuous output given in  
the Absolute Maximum Ratings table in this  
data sheet, or higher purely transient currents.
