description
The SN74F260 contains two independent 5-input
positive-NOR gates. It performs the Boolean
functions Y = A + B + C + D + E in positive logic.
The SN74F260 is characterized for operation from
0°C to 70°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 voltage ratings may be exceeded provided the input current ratings are observed.
