54LS153/DM54LS153/DM74LS153

Dual 4-Line to 1-Line Data Selectors/Multiplexers

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

n lines)

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.

High fan-out, low impedance, totem pole outputs

Typical average propagation delay times

Ð From data 14 ns

Ð From strobe 19 ns

Ð From select 22 ns

Typical power dissipation 31 mW

Alternate Military/Aerospace device (54LS153) is avail-

able. Contact a National Semiconductor Sales Office/

Distributor for specifications.

Features

Permits multiplexing from N lines to 1 line

Performs at parallel-to-serial conversion

Absolute Maximum Ratings (Note)

If Military/Aerospace specified devices are required,

please contact the National Semiconductor Sales

Office/Distributors for availability and specifications.

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.
