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-NOR gates. They perform the Boolean
functions Y = A + B
The SN54ALS02A and SN54AS02 are
characterized for operation over the full military
temperature range of –55°C to 125°C. The
SN74ALS02A and SN74AS02 are characterized
for operation from 0°C to 70°C.
