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.
