description
These devices contain two independent 4-input
AND gates. They perform the Boolean functions
Y = A
SBSCSD or Y = A + B + C + D in positive logic.
The 54ACT11021 is characterized for operation
over the full military temperature range of − 55
°C
to 125
°C. The 74ACT11021 is characterized for
operation from − 40
°C to 85°C.
