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
■Select one-of-eight data lines
■Performs parallel-to-serial conversion
■Permits multiplexing from N lines to one line
■Also for use as Boolean function generator
■Typical average propagation delay time, data input to W output 4.5 ns
■Typical power dissipation 225 mW
