description

These data selectors/multiplexers contain
inverters and drivers to supply fully
complementary binary decoding data selection to
the AND-OR-invert gates. Separate strobe (G

)
inputs are provided for each of the two 4-line
sections.

The SN54ALS352 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74ALS352 is characterized for
operation from 0°C to 70°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.
