Chips dissipation power problem

In the use of chip or system of power supply, chip or system power dissipation (
The power dissipation
) is
A very concern and, in some cases, it can directly relates to whether a system works.

The chip
The Spec
Generally has dissipation power on this parameter. Such as chip

, it's
Datasheet
In the
There are the following parameters:

Any TTL
Or CMOS
Components are under certain junction temperature, and the chip with the increase of power consumption, the temperature gradually
Rose, when reaching the maximum junction temperature, power is the power dissipation of the chip and now.The power consumption of general use chip
P = I2R or P = UI (linear) under the condition to calculate
