54LS153 DM54LS153 DM74LS153
Dual 4-Line to 1-Line Data Selectors Multiplexers
General Description
Each of these data selectors multiplexers contains invert-
ers and drivers to supply fully complementary on-chip bina-
ry decoding data selection to the AND-OR-invert gates
Separate strobe inputs are provided for each of the two
four-line sections
Features
Y Permits multiplexing from N lines to 1 line
Y Performs at parallel-to-serial conversion
Y Strobe (enable) line provided for cascading (N lines to
n lines)
Y High fan-out low impedance totem pole outputs
Y Typical average propagation delay times
From data 14 ns
From strobe 19 ns
From select 22 ns
Y Typical power dissipation 31 mW
Y Alternate Military Aerospace device (54LS153) is avail-
able Contact a National Semiconductor Sales Office
Distributor for specifications
