DM74LS153 Dual 1-of-4 Line Data Selectors/Multiplexers
DM74LS153
Dual 1-of-4 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 strob e inputs ar e provided for each of the
two four-line sections.
Features
■ Permits multiplexing from N lines to 1 line
■ Performs at parallel-to-serial conversion
■ Strobe (enable) line provided for cascading
(N lines to n lines)
■ High fan-out, low impedance, totem pole outputs
■ Typical average propagation delay times
From data 14 ns
From strobe 19 ns
From select 22 ns
■ Typical power dissipation 31 mW
Ordering Code:
Devices also availab le in Tape and Reel. Specify by appending th e s uffix let t er “X” to the ordering code.
Connection Diagram Function Table
Select inputs A and B are common to both sections.

Absolute Maximum Ratings(Note 1)
Note 1: The “Absolute Maximum Ratings ” are those val ues beyond w hich
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 “Recommend ed O peratin g Cond itions” t able w ill defin e the condition s
for actual device operation.
