8.0 Thermal Characteristics

The following table displays the thermal characteristics of various packages

The Junction Temperature

θj, can be calculated using the following equation

θj = P*θJa + θa

where,

P = Power

θJa = Junction to Ambient Temperature (θJc + θCa)

θa = Ambient Temperature (70 C)

The Case Temperature

θc, can be calculated using the following equation

θc = P*θCa + θa

where,

P = Power

θCa = Case to Ambient Temperature

θa = Ambient Temperature (70 C)

Notes:

15. It is recommended to not power I/O with chip power off.
