DM74ALS151 1 of 8 Line Data Selector/Multiplexer April 1984 Revised February 2000 DM74ALS151 1 of 8 Line Data Selector/Multiplexer General Description This Data Selector/Multiplexer contains full on-chip decoding to select one-of-eight data sources as a result of a unique three-bit binary code at the Select inputs. Two complementary outputs provide both inverting and non-inverting 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 s Advanced oxide-isolated, ion-implanted Schottky TTL process s Switching performance is guaranteed over full temperature and VCC supply range s Pin and functional compatible with LS family counterpart s Improved output transient handling capability Ordering Code: Order Number DM74ALS151M DM74ALS151N Package Number M16A N16E Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

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.
