4. See MIL-STD-883 for environmental screening options.

5. Faster switching speed can be achieved with enhanced driver waveform.

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.

Truth Table

6,7

6. 0 = 0 V to -0.2 V, 1 = -5 V to -8 V

7. When an RF output port is “off” it is shorted to ground

through an “on” shunt MESFET.
