# WARNING
The functionality of the I.C. is guaranted in this voltage range. Nevertheless the specified operating voltages (VDC, VDD, VDL), must be selected
according to the load characteristics. Proper cautions must be taken in the application in order to assure that the drain-source voltage across
each output power transistor does not exceed 20V max.

(*) WARNING
These current values are compatible with the structure of the IC power structure. Nevertheless the use of these current levels could produce
junction temperatures that force IC outside of the operative range due to the thermal characteristics of the choosen package.
