Sales office that you have the latest data sheet be-
fore finalizing a design
WARNING Stressing the device beyond the ‘‘Absolute
Maximum Ratings’’ may cause permanent damage
These are stress ratings only Operation beyond the
‘‘Operating Conditions’’ is not recommended and ex-
tended exposure beyond the ‘‘Operating Conditions’’
may affect device reliability
Maximum Power Dissipation V_CC3
470 mW
The Maximum total power dissipation in the
82434NX on the V_CC and V_CC3 pins is 2 0W The
V_CC3 pins may draw as much as 470 mW however
total power will not exceed 2 0W
9 2 Thermal Characteristics
The 82434LX and 82434NX PCMCs are designed
