TL F 639354LS153 DM54LS153 DM74LS153 Dual 4-Line to 1-Line Data Selectors Multiplexers
June1989 54LS153 DM54LS153 DM74LS153
Dual4-Line to1-Line Data Selectors Multiplexers
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
Features
Y Permits multiplexing from N lines to1line
Y Performs at 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 data14ns
From strobe19ns
From select22ns
Y Typical power dissipation31mW
Y Alternate Military Aerospace device(54LS153)is avail-
able Contact a National Semiconductor Sales Office
