DM74ALS151 1 of 8 Line Data Selector/Multiplexer
DM74ALS151
1 of 8 Line Data Selector/Multiplexer
General Description
This Data Selector/Multiplexer contains full on-chip decod-
ing to select one-of-eight data sources as a result of a
unique three-bit binary code at the Select inputs. Two com-
plementary outputs provide both inverting and non-invert-
ing buffer operation. A Strobe input is provided which,
when at the high level, disables all data inputs and forces
the Y output to the LOW state and the W output to the
HIGH state. The Select input buffers incorporate internal
overlap features to ensure that select input changes do not
cause invalid output transients.
Features
■ Advanced oxide-isolated, ion-implanted Schottky TTL
process
■ Switching performance is guaranteed over full tempera-
ture and V
CC
supply range
■ Pin and functional compatible with LS family counterpart
■ Improved output transient handling capability
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Absolute Maximum Ratings(Note 1)
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.
