MC10164
APPLICATION INFORMATION
The MC10164 can be used wherever data multiplexing or
parallel to serial conversion is desirable. Full parallel gating
permits equal delays through any data path. The output of
the MC10164 incorporates a buffer gate with eight data
inputs and an enable. A high level on the enable forces the
output low. The MC10164 can be connected directly to a
data bus, due to its open emitter output and output enable.
Figure 1 illustrates how a 1–of–64 line multiplexer can be
built with eight MC10164’s wire ORed at their outputs and
one MC10161 to drive the enables on each multiplexer,
without speed degradation over a single MC10164 being
experienced.
