uncomfortable with unwanted reflections on the line. To
better match the impedances when driving multiple lines,
the situation in Figure 4 “Optimized Dual Line
Termination” should be used. In this case, the series
terminating resistors are reduced such that when the
parallel combination is added to the output buffer
impedance the line impedance is perfectly matched.
