QUADRUPLE 2-INPUT POSITIVE-NOR GATES
SDAS111B – 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-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.

None: Not yet available Lead (Pb-Free).
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
