Separate strobe output-enable (1OE or 2OE) inputs are provided for each of the two four-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 (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. The output is disabled when its strobe is high. The 74AC11353 is characterized for operation from – 40°C to 85°C.
