Dual 4-Input Positive-AND Gates
descriptionThese 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.
