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

permanent damage to this device.

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

these survivability limits.

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

signal is applied prior to power supply.

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.
