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

Note
The ``Absolute Maximum Ratings'' are those values
beyond which the safety of the device cannot be guaran-
teed The device should not be operated at these limits The
parametric values defined in the ``Electrical Characteristics''
table are not guaranteed at the absolute maximum ratings
The ``Recommended Operating Conditions'' table will define
the conditions for actual device operation
