cause any false clock triggering; however, designers may be
uncomfortable with unwanted reflections on the line. To better
match the impedances when driving multiple lines the situation
in
this case the series terminating resistors are reduced such that
when the parallel combination is added to the output buffer im-
pedance the line impedance is perfectly matched.
