DM74LS151 1-of-8 Line Data Selector/Multiplexer
General Description
This data selector/multiplexer contains full on-chip decoding 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 output HIGH, and the Y output LOW. The DM74LS151 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 12.5 ns s Typical power dissipation 30 mW
