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.
