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.
