† 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.

These devices of the SN74F27 contain three independent 3-input NOR gates. They perform the Boolean functions Y = A • B • C or Y = A + B + C in positive logic.

The SN54F27 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74F27 is characterized for operation from 0°C to 70°C.
