Handling Procedures
5. Exceeding any one or combination of these limits may cause
permanent damage to this device.
6. MACOM 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 = +66°C @ 5 V, 110 mA
b) For TA = +85°C,
TJ = +122°C @ 5 V, 100 mA
Schematic Including Off-Chip Components9
Please observe the following precautions to avoid
damage:
Static Sensitivity
These electronic devices 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 inexpensive anti
-parallel diode pair can be used to protect the IC.
Please reference application note AN3028 on
http://www.macomtech.com for further detail.
