description

These devices contain six independent 2-input

NAND

drivers.

They

perform

the

Boolean

functions Y = A

• B or Y = A + B in positive logic.

The

SN54ALS804A

and

SN54AS804B

are

characterized for operation over the full military

temperature range of – 55

°C to 125°C. The

SN74ALS804A

and

SN74AS804B

are

characterized for operation from 0

°C to 70°C.
