*Stresses above 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 above those indi-

cated in the operation sections of the specifications is not

implied. Exposure to Absolute Maximum Rating conditions

for extended periods my affect device reliability.

See "Output Clamp" discussion.

Output clamp not connected. See typical characteristics curves for output swing versus clamp current characteristics.

Limiting input current to 100A is recommended to avoid latch-up problems.
