DM74ALS153
Dual 1-of-4 Line Data Selector/Multiplexer
General Description
This Data Selector/Multiplexer contains full on-chip decod-
ing to select one-of-four data sources as a result of a
unique two-bit binary code at the Select inputs. Each of the
two Data Selector/Multiplexer circuits have their own sepa-
rate Data and Strobe inputs and a non-inverting output
buffer. The Select inputs A and B are common to both sec-
tions. The Strobe inputs, when at the HIGH level, disable
their associated data inputs and force the corresponding
output to the LOW state. The Select input buffers incorpo-
rate internal overlap features to ensure that select input
changes do not cause invalid output transients.

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.
