DM74S151
1-of-8 Data Selector/Multiplexer
with Complementary Outputs
General Description
These data selectors/multiplexers contain full on-chip
decoding to select the desired data source. The
DM74S151 selects one-of-eight data sources. The
DM74S151 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 output HIGH and the Y output LOW.
The DM74S151 features complementary W and Y outputs.
Features
s Select one-of-eight data lines
s Performs parallel-to-serial conversion
s Permits multiplexing from N lines to one line
s Also for use as Boolean function generator
s Typical average propagation delay time, data input to W
output 4.5 ns
s Typical power dissipation 225 mW
