description
These devices contain six independent 2-input
NOR drivers. They perform the Boolean functions
Y = A + B or Y = A
B in positive logic.
The
SN54ALS805A
and
SN54AS805B
are
characterized for operation over the full military
temperature range of 55
°C to 125°C. The
SN74ALS805A
and
SN74AS805B
are
characterized for operation from 0
°C to 70°C.
