54LS352 DM74LS352 Dual 4-Line to
1-Line Data Selectors Multiplexers
General Description
Each of these data selectors multiplexers contains invert-
ers and drivers to supply fully complementary on-chip bi-
nary decoding data selection to the AND-OR-invert gates
Separate strobe inputs are provided for each of the two
four-line sections
Features
Y Inverting version of DM54 74LS153
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 15 ns
From strobe 19 ns
From select 22 ns
Y Typical power dissipation 31 mW
