description
These devices contain 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
