These data selectors/multiplexers contain full

binary decoding to select 1-of-8 data sources and

feature strobe-controlled complementary 3-state

outputs.

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. Both outputs are controlled by

the output-enable (OE) input. The outputs are

disabled when OE is high.
