DM74LS153
Dual 1-of-4 Line Data Selectors/Multiplexers
General Description
Each of these data selectors/multiplexers contains invert-
ers 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
14 ns
From strobe
19 ns
From select
22 ns
s
Typical power dissipation 31 mW
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter "X" to the ordering code.

Absolute Maximum Ratings
(Note 1)
Note 1: 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 tables are not guaranteed at the absolute maximum ratings.
The "Recommended Operating Conditions" table will define the conditions
for actual device operation.
