description
These devices contain four independent 2-input NOR gates. They perform the Boolean functions Y = ASB or Y = A + B in positive logic.
The 54ACT11002 is characterized for operation over the full military temperature range of – 55°C to 125°C. The 74ACT11002 is characterized for operation from – 40°C to 85°C.
