description
These devices contain two independent 4-input
positive-AND gates. They perform the Boolean
functions Y = A
B C D or Y = A + B + C + D
in positive logic.
The
SN54ALS21A
and
SN54AS21
are
characterized for operation over the full military
temperature range of 55
°C to 125°C. The
SN74ALS21A and SN74AS21 are characterized
for operation from 0
°C to 70°C.
