The number of output drivers ON and conducting (m) may
be from 1 to n. (i.e., For all 8 output drivers conducting, m = n
= 8.) Maximum temperature, dissipation and current ratings
must be observed. The drain current vs case temperature
may be plotted for any value of m from 1 to 8, provided drain
currents remain equal.
