9. Logic “1” for VDD = +5 volts and VC = +3.3 volts typical.
5. Exceeding any one or combination of these limits may cause
permanent damage to this device.
6. M/A-COM Technology Solutions does not recommend
sustained operation near these survivability limits.
7. These operating conditions will ensure MTTF > 1 x 106 hours.
8. Junction Temperature (TJ) = TA + Өjc * (V * I)
Typical thermal resistance (Өjc) = 73 °C/W.
a) For TA = 25°C,
TJ = 72 °C @ 5.0 V, 130 mA
b) For TA = 85°C,
TJ = 129 °C @ 5.0 V, 120 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. An external protection circuit using an
anti-parallel diode pair can be used to protect the
IC.
Please reference application note AN3028 on
http://www.macomtech.com for further detail.
