54LS151/DM54LS151/DM74LS151
Data Selector/Multiplexer
General Description
This data selector/multiplexer contains full on-chip decoding
to select the desired data source. The 'LS151 selects
one-of-eight data sources. The 'LS151 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 'LS151 features complementary W and Y outputs.
Features
Y Select one-of-eight data lines
Y Performs parallel-to-serial conversion
Y Permits multiplexing from N lines to one line
Y Also for use as Boolean function generator
Y Typical average propagation delay time data input to W
output 12.5 ns
Y Typical power dissipation 30 mW
Y Alternate Military/Aerospace device (54LS151) is available.
Contact a National Semiconductor Sales Office/
Distributor for specifications.
