1 of 8 Line Data SelectorMultiplexer

General Description

This Data SelectorMultiplexer contains full on-chip decod-

ing to select one-of-eight data sources as a result of a

unique three-bit binary code at the Select inputs Two com-

plementary outputs provide both inverting and non-inverting

buffer operation A Strobe input is provided which when at

the high level disables all data inputs and forces the Y out-

put to the low state and the W output to the high state The

Select input buffers incorporate internal overlap features to

ensure that select input changes do not cause invalid output

transients
