The 3-state outputs can interface with and drive

data lines of bus-organized systems. With all but

one of the common outputs disabled (at 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.
