description
Each of these data selectors/multiplexers contains inverters and drivers to supply full binary decoding data
selection to the AND-OR gates. 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.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
