description
These devices contain three independent 3-input NOR gates. They perform the Boolean functions Y = A + B + C or Y = ASBSC in positive logic. The 54ACT11027 is characterized for operation over the full military temperature range of 55°C to 125°C. The 74ACT11027 is characterized for operation from 40°C to 85°C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
