description

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 four-line sections.

The three-state outputs can interface with and

drive data lines of bus-organized systems. With

all but one of the common outputs disabled (at a

high-impedance state), the low-impedance of the

single enabled output will drive the bus line to a

high or low logic level. Each output has its own

strobe (G). The output is disabled when its strobe

is high.
