NOTES:

1. Stresses beyond those listed 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.

2. The performance capability of a high–performance integrated circuit in conjunction with its thermal environment can create junction

temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.

3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
