SWCS046U –MARCH 2010–REVISED JUNE 2014
Recommended Operating Conditions (continued)
over operating free-air temperature range (unless otherwise noted)
Note 1: VCC7 should be connected to the highest supply that is connected to the device VCCx pin. The exception is that
VCC2 and VCC4 can be higher than VCC7.
Note 2: VCC2 and VCC4 must be connected together (to the same voltage).
Note 3: If VDD3 boost is used, VAUX33 must be set to 2.8 V or higher and enabled before VDD3.

(1) °C/W = degrees Celsius per watt.
(2) These values are based on a JEDEC-defined 2S2P system (with the exception of the Theta JC [RΘ
JC
] value, which is based on a
JEDEC-defined 1S0P system) and will change based on environment as well as application. For more information, see these
EIA/JEDEC standards:
• JESD51-2, Integrated Circuits Thermal Test Method Environmental Conditions - Natural Convection (Still Air)
• JESD51-3, Low Effective Thermal Conductivity Test Board for Leaded Surface Mount Packages
• JESD51-7, High Effective Thermal Conductivity Test Board for Leaded Surface Mount Packages
• JESD51-9, Test Boards for Area Array Surface Mount Package Thermal Measurements
(3) m/s = meters per second.
