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 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 electric ity. Proper ESD control techniques should be used when handling these devices.
