description
The 74ACT11802 contains three independent 4-input OR/NOR gates. They perform the Boolean functions in
positive logic Y = A + B + C + D and Z = A + B + C + D.
The 74ACT11802 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 clamp-current ratings are observed.
