54153/DM54153/DM74153 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
Y Permits multiplexing from N lines to 1 line
Y Performs 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 11 ns
From strobe 18 ns
From select 20 ns
Y Typical power dissipation 170 mW
Y Alternate Military/Aerospace device (54153) is available.
Contact a National Semiconductor Sales Office/
Distributor for specifications.
