DM74LS151
1-of-8 Line Data Selector/Multiplexer
General Description
This data selector/multiplexer contains full on-chip decod-
ing to select the desired data source. The DM74LS151
selects one-of-eight data sources. The DM74LS151 has a
strobe input which must be at a low logic level to enable
these devices. A high level at the strobe forces the W out-
put HIGH, and the Y output LOW.
The DM74LS151 features complementary W and Y out-
puts.
