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.
