Dual 4-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs
Low Power Consumption, 80-µA Max ICC Typical tpd = 9 ns ±6-mA Output Drive at 5 V
Low Input Current of 1 µA Max Permit Multiplexing From n Lines to OneLine Perform Parallel-to-Serial Conversion
description/ordering informationEach of these data selectors/multiplexers
contains inverters and drivers to supply full binary
decoding data selection to the AND-OR gates.
Separate output-control inputs are provided for
each of the two 4-line sections.
The 3-state outputs can interface with and drive
data lines of bus-organized systems. With all but
one of the common outputs disabled (in the
high-impedance state), the low impedance of the
single enabled output drives the bus line to a high
or low logic level. Each output has its own
output-enable (OE) input. The outputs are
disabled when their respective OE is high.
