NOTE:
For applications which use the LVI, Motorola guarantee the functionality
of the device down to the LVI trip point (V_LVI) within the constraints
outlined in Low Voltage Inhibit (LVI) on page 195.

NOTES:
1. Power dissipation is a function of temperature.
2. K is a constant unique to the device. K can be determined from a known T_A and measured
P_D. With this value of K, P_D, and T_J can be determined for any value of T_A.
