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.
SN54ALS21A, SN54AS21, SN74ALS21A, SN74AS21 DUAL 4ĆINPUT POSITIVEĆAND GATES • Package Options Include Plastic Small-Outline (D) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil.
