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.
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.
