unusually high pin current (heavy loads), the difference between pin voltage and VSS or VDD will be very
small.
The average chip-junction temperature (TJ) in
°C can be obtained from:
TJ = TA + (PD × θJA)
Eqn. 1
where:
TA = Ambient temperature, °C
θJA = 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 << 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) + θJA× (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 a known TA. Using this value of K, the values of PD and TJ can be obtained by
solving Equation 1 and Equation 2 iteratively for any value of TA.

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 used 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.
