Each 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.
