TJ = TA + (PD JA)
Eqn. 1
where:
TA = Ambient temperature, C
JA = Package thermal resistance, junction-to-ambient, C/W
PD = Pint PI/O
Pint = IDD VDD, Watts — chip internal power
PI/O = Power dissipation on input and output pins — user determined
For most applications, PI/O far much smaller than Pint and can be neglected. An approximate relationship
between PD and TJ (if PI/O is neglected) is:
PD = K (TJ + 273 C)
Eqn. 2
Solving Equation 1 and Equation 2 for K gives:
K = PD (TA + 273 C) + JA (PD)
2
Eqn. 3
where K is a constant pertaining to the particular part. K can be determined from Equation 3 by measuring
PD (at equilibrium) for an known TA. Using this value of K, the values of PD and TJ can be obtained by

ESD Protection and Latch-Up Immunity
Although damage from electrostatic discharge (ESD) is much less common on these devices than on early
CMOS circuits, normal handling precautions must be taken to avoid exposure to static discharge.
Qualification tests are performed to ensure that these devices can withstand exposure to reasonable levels
of static without suffering any permanent damage.
During the device qualification, ESD stresses were performed for the human body model (HBM) and the
charge device model (CDM).
A device is defined as a failure if after exposure to ESD pulses the device no longer meets the device
specification. Complete DC parametric and functional testing is performed per the applicable device
specification at room temperature followed by hot temperature, unless instructed otherwise in the device
specification.
