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

Note The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaran-
teed The device should not be operated at these limits The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation
