4. Exceeding any one or combination of these limits may cause permanent damage to this device.
5. M/A-COM does not recommend sustained operation near these survivability limits.
6. These operating conditions will ensure MTTF > 1 x 106 hours.
7. Junction Temperature (TJ) = TA + Өjc * (V * I)
Typical thermal resistance (Өjc) = 148 °C/W.
a) For TA = 25°C,
TJ = 69 °C @ 5.0 V, 60 mA
b) For TA = 85°C,
TJ = 126 °C @ 5.0 V, 55 mA
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.
