Separate output control inputs are provided for each of the two four-line sections. Use the three-state outputs to drive data lines in bus-organized systems. With all but one of the common outputs disabled the low-impedance of the single enable output will drive the bus line to a high or low logic level. Each output has its own strobe (G). The devices are characterized over full military temperature range of -55°C to +125°C.
