The SN54F02 and SN74F02 are four independent 2-input NOR gates. They perform the Boolean functions Y = A + B or Y = A • B in positive logic. The SN54F02 is characterized for operation over the full military temperature range of –55°C to 125°C. The SN74F02 is characterized for operation from 0°C to 70°C.
The SN54F02 and SN74F02 devices each contain four independent 2‑input positive‑NOR gates. They operate in positive logic, performing the Boolean function Y = A·B + A·B. The SN54F02 is rated for the full military temperature range (‑55 °C to 125 °C) while the SN74F02 is specified for 0 °C to 70 °C.
