66-MHz Electrical Characteristics
An estimation of the chip junction temperature, T
where:
The junction to ambient thermal resistance is an industry standard value which provides a quick and easy
estimation of thermal performance. Unfortunately, the answer is only an estimate; test cases have
demonstrated that errors of a factor of two are possible. As a result, more detailed thermal characterization
is supplied.
Historically, the thermal resistance has frequently been expressed as the sum of a junction to case thermal
resistance and a case to ambient thermal resistance:

Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site
(board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and
the board thermal resistance.
Per SEMI G38-87 and JESD51-2 with the board horizontal.
These values are the mean + 3 standard deviations of characterized data.
Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site
(board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and
the board thermal resistance.
Per JESD51-6 with the board horizontal.
Thermal resistance between the die and the printed circuit board (Four layer (2s2p) board, natural convection).
Indicates the thermal resistance between the die and the case top surface as measured by the cold plate
method (MIL SPEC-883 Method 1012.1) with the cold plate temperature used for the case
temperature.
