DM74150, DM74151A
Data Selectors/Multiplexers
General Description
These data selectors/multiplexers contain full on-chip decod-
ing 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,
whereas the 150 has an inverted (W) output only.
The 151A incorporates address buffers which have sym-
metrical propagation delay times through the complementary
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
n150 selects one-of-sixteen data lines
n151A selects one-of-eight data lines
nPerforms parallel-to-serial conversion
nPermits multiplexing from N lines to one line
nAlso for use as Boolean function generator
nTypical average propagation delay time, data input to W
output
150 11 ns
151A 9 ns
nTypical power dissipation
150 200 mW

nAlternate Military/Aerospace device (54150, 54151A) is
available. Contact a Fairchild Semiconductor Sales
Office/Distributor for specifications.

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” table are not guaranteed at the absolute maximum ratings. The “Recommended Operating
Conditions” table will define the conditions for actual device operation.
