The average chip-junction temperature (TJ) in C can be obtained from
Eqn. 1
where
TA = ambient temperature, C
JMA = package thermal resistance, junction-to-ambient, C/W
PD =PINT + PI/O
PINT = chip internal power, IDD VDD, watts
PI/O = power dissipation on input and output pins — user determined
For most applications, PI/O < PINT and can be ignored. An approximate relationship between PD and TJ (if PI/O is neglected) is:
Eqn. 2
Solving equations 1 and 2 for K gives:
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
Table 21. ESD Protection Characteristics1
1 A device is defined as a failure if the device no longer meets the device specification requirements after
exposure to ESD pulses. Complete DC parametric and functional testing is performed per applicable device
specification at room temperature followed by hot temperature, unless specified otherwise in the device
specification.
