THERMAL INFORMATION
The maximum power consumption an integrated circuit
can tolerate at a given operating ambient temperature can be
found from the equation:
This must be greater than the sum of the products of the
supply voltages and supply currents at the worst case
operating condition.

= Maximum operating junction temperature
as listed in the maximum ratings section.

temperature.
