Triple 3-input positive-NOR gates
descriptionThese devices 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.
