DM74150
Data Selectors/Multiplexers
General Description
Features
These data selectors/multiplexers contain full on-chip
decoding to select the desired data source. The DM74150
selects one-of-sixteen data sources. The DM74150 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 (as applicable) LOW.
■ 150 selects one-of-sixteen data lines
The DM74150 features an inverted (W) output only.
■ Performs parallel-to-serial conversion
■ Permits multiplexing from N lines to one line
■ Also for use as Boolean function generator
■ Typical average propagation delay time, data input to W
output: 11 ns
■ Typical power dissipation: 200 mW

Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
