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 (OE) inputs are provided for each of the two four-line sections. The 74ACT11352 is characterized for operation from - 40C to 85C.

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.
