Note 1:
T_{A (MAX)} = 125°C for part suffix MFU
T_{A (MAX)} = 105°C for part suffix VFU
T_{A (MAX)} = 85°C for part suffix CFU
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).

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.
