description

These devices contain six independent 2-input
AND drivers. They perform the Boolean functions
Y = A • B or Y = A

+ B in positive logic.

The SN54AS808B is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74AS808B is characterized for
operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
