Thermal characteristics

The maximum chip junction temperature (TJ max) must never exceed the values given in

Operating conditions

The maximum chip-junction temperature, TJmax, in degrees Celsius, may be calculated using

the following equation:

TJmax = TAmax + (PDmax x ΘJA)

Where:

• TAmax is the maximum ambient temperature in °C

• ΘJA is the package junction-to-ambient thermal resistance in ° C/W

• PDmax is the sum of PINTmax and PI/Omax (PDmax = PINTmax + PI/Omax)

• PINTmax is the product of IDD andVDD, expressed in Watts. This is the maximum chip internal

power.

• PI/Omax represents the maximum power dissipation on output pinsWhere:PI/Omax =Σ (VOL*IOL)

+ Σ((VDD-VOH)*IOH), taking into account the actual VOL/IOL and VOH/IOH of the I/Os at low

and high level in the application.
