description
These devices contain four independent 2-input
positive-AND gates. They perform the Boolean
functions Y = A B or Y = A + B in positive logic.
The SN54ALS08 and SN54AS08 are
characterized for operation over the full military
temperature range of − 55°C to 125°C. The
SN74ALS08 and SN74AS08 are 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.
