Note: Absolute maximum ratings indicate limits beyond
which damage to the device may occur. DC and AC electrical
specifications are not ensured when operating the device at
absolute maximum ratings. * The latch-up tolerance on Ac-
cess Bus pins 14 and 15 meets 150mA.

and can be neglected.
3. K is a constant pertaining to the device. Solve for K with a known T
A
and a measured P
D
(at equilibrium). Use this value of K to solve for
P

and T
J
iterntively for any value of T
