Packaging Information
In Brief . . .
The packaging availability for each device type is indicated
on the individual data sheets and the Selector Guide. All of the
outline dimensions for the packages are given in this section.
The maximum power consumption an integrated circuit
can tolerate at a given operating ambient temperature can be
found from the equation:
T
– T
A
J(max)
P
=
D(TA)
R
θJA(Typ)
where:
P
= Power Dissipation allowable at a given
operating ambient temperature. This must
be greater than the sum of the products of
the supply voltages and supply currents at
the worst case operating condition.
D(TA)
T
= Maximum operating Junction Temperature
as listed in the Maximum Ratings Section.
J(max)
See individual data sheets for T
information.
J(max)
T
A
= Maximum desired operating Ambient
Temperature
R
= Typical Thermal Resistance Junction-to-
Ambient
