Package Thermal Characteristics
The device junction to case thermal characteristic is
θjc, and the junction to ambient air characteristic is
θja. The thermal characteristics for θja are shown with two different air flow rates.
Maximum junction temperature is 150
°C.
A sample calculation of the absolute maximum power dissipation allowed for a PQ160 package at
commercial temperature and still air is as follows:
EQ 1
Power Dissipation
P = [ICC standby + ICCactive] * VCC + IOL * VOL * N + IOH* (VCC – VOH) * M
EQ 2
where:
ICC standby is the current flowing when no inputs or outputs are changing
ICCactive is the current flowing due to CMOS switching.
IOL and IOH are TTL sink/source currents.
VOL and VOH are TTL level output voltages.
N is the number of outputs driving TTL loads to VOL.
M is the number of outputs driving TTL loads to VOH.
An accurate determination of N and M is problematical because their values depend on the family type,
design details, and on the system I/O. The power can be divided into two components: static and active.
