Data Selectors Multiplexers
General Description
These data selectors multiplexers contain full on-chip de-
coding to select the desired data source The 150 selects
one-of-sixteen data sources the 151A selects one-of-eight
data sources The 150 and 151A have 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
(as applicable) low
The 151A features complementary W and Y outputs where-
as the 150 has an inverted (W) output only
The 151A incorporates address buffers which have sym-
metrical propagation delay times through the complementa-
ry paths This reduces the possibility of transients occurring
at the output(s) due to changes made at the select inputs
even when the 151A outputs are enabled (i e strobe low)
Features
Y 150 selects one-of-sixteen data lines
Y 151A selects 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
150 11 ns
151A 9 ns
Y Typical power dissipation
150 200 mW
151A 135 mW
Y Alternate Military Aerospace device (54150 54151A) is
available Contact a National Semiconductor Sales Of-
fice Distributor for specifications
