54LS153/DM54LS153/DM74LS153

Dual 4-Line to 1-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

YPermits multiplexing from N lines to 1 line

YPerforms at parallel-to-serial conversion

Y Strobe (enable) line provided for cascading (N lines to n lines)

YHigh fan-out, low impedance, totem pole outputs

YTypical average propagation delay times

ÐFrom data 14 ns

ÐFrom strobe 19 ns

ÐFrom select 22 ns

YTypical power dissipation 31 mW

YAlternate Military/Aerospace device (54LS153) is available. Contact a National Semiconductor Sales Office/ Distributor for specifications.

Absolute Maximum Ratings (Note)

If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/Distributors for availability and specifications.

Supply Voltage	7V
Input Voltage	7V
Operating Free Air Temperature Range	b55§C to a125§C
DM54LS and 54LS
DM74LS	0§C to a70§C
Storage Temperature Range	b65§C to a150§ C

Note: The ``Absolute Maximum Ratings'' are those values beyond which the safety of the device cannot be guaranteed. 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.
