Handling Procedures

Please observe the following precautions to avoid

damage:

Static Sensitivity

Gallium Arsenide Integrated Circuits are sensitive

to electrostatic discharge (ESD) and can be

damaged by static electricity. Proper ESD control

techniques should be used when handling these

devices.

Moisture Sensitivity

The MSL rating for this part is defined as Level 2

per IPC/JEDEC J-STD-020. Parts shall be stored

and/or baked as required for MSL Level 2 parts.
