description
These devices contain four independent 2-input NOR gates. They perform the Boolean function Y = A + B or Y = A · B in positive logic. The SN54HC02 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74HC02 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. NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length of zero.
