2. Exceeding any one or combination of these limits may cause

permanent damage to this device.

3. M/A-COM does not recommend sustained operation near

these survivability limits.

4. Standard CMOS TTL interface, latch-up will occur if logic sig-

nal is applied prior to power supply.

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.
