DM54S151/DM74S151 1-of-8 Data Selector/Multiplexer
with Complementary Outputs
General Description Features
These data selectors/multiplexers contain full on-chip de- ll Select one-of-eight data lines
coding to select the desired data source. The 'Sl 51 selects ll Performs parallel-tmserial conversion
one-of-eight data sources. The 'S151 has a strobe input a Permits multiplexing from N lines to one line
whiph must be at a low logic level to enable these devices. I, Also for use as Boolean function generator
A high level at the strobe forces the W output high and the Y n Typical average propagation delay time, data input to W
output low. output 4.5 ns
The 'S151 features complementary W and Y outputs. a Typical power dissipation 225 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.
