Revised February 2000 DM74ALS153 Dual 1-of-4 Line Data Selector/Multiplexer General Description Features This Data Selector/Multiplexer contains full on-chip decoding 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 separate Data and Strobe inputs and a non-inverting output buffer. The Select inputs A and B are common to both sections. 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 incorporate internal overlap features to ensure that select input changes do not cause invalid output transients. ■ Advanced oxide-isolated, ion-implanted Schottky TTL process ■ Switching performance is guaranteed over full temperature and VCC supply range ■ Pin and functional compatible with LS family counterpart ■ Improved output transient handling capability Ordering Code: Order Number Package Number Package Description DM74ALS153M M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow DM74ALS153SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide DM74ALS153N N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
