permanent damage to this device.
6. M/A-COM Technology Solutions does not recommend
sustained operation near these survivability limits.
7. Operating at nominal conditions with TJ ≤ +150°C 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 = 95 °C @ 5.0 V, 190 mA
b) For TA = 85°C,
TJ = 149 °C @ 5.0 V, 175 mA

9. VCONTROL for Logic “1” = +3 to +5 volts, Logic “0” = 0 ± 0.2 volts.
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.
