Data Selector Multiplexer
General Description
This data selector multiplexer contains full on-chip decod-
ing 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 avail-
able Contact a National Semiconductor Sales Office
