| DM74LS153 Dual 1-of-4 Line Data Selectors/Multiplexers August 1986 Revised March 2000 DM74LS153 Dual 1-of-4 Line Data Selectors/Multiplexers General Description Each of these data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR-invert gates. Separate strobe inputs are provided for each of the two four-line sections. Features s Permits multiplexing from N lines to 1 line s Performs at parallel-to-serial conversion s Strobe (enable) line provided for cascading (N lines to n lines) s High fan-out, low impedance, totem pole outputs s Typical average propagation delay times From data From strobe From select 14 ns 19 ns 22 ns s Typical power dissipation 31 mW Ordering Code: Order Number DM74LS153M DM74LS153N 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.
