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 one 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.
