QUADRUPLE 2-INPUT POSITIVE-AND GATES
SDAS191A – APRIL 1982 – REVISED DECEMBER 1994
• Package Options Include Plastic
Small-Outline (D) Packages, Ceramic Chip
Carriers (FK), and Standard Plastic (N) and
Ceramic (J) 300-mil DIPs
description
These devices contain four independent 2-input
positive-AND gates. They perform the Boolean
functions Y = A • B or Y = A
The SN54ALS08 and SN54AS08 are
characterized for operation over the full military
temperature range of –55°C to 125°C. The
SN74ALS08 and SN74AS08 are characterized for
operation from 0°C to 70°C.
