description
These devices contain three independent 3-input
NOR gates. They perform the Boolean functions
Y = A + B + C or Y = A S B S C in positive logic.
The 54AC11027 is characterized for operation
over the full military temperature range of − 55°C
to 125°C. The 74AC11027 is characterized for
operation from −40°C to 85°C.
