description
These devices contain six independent 2-input
NAND drivers. They perform the Boolean
functions Y = A
• B or Y = A + B in positive logic.
The SN54ALS804A and SN54AS804B are
characterized for operation over the full military
temperature range of –55°C to 125°C. The
SN74ALS804A and SN74AS804B 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.
