Handling Procedures
The following precautions should be observed 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.

Optional current control⁶
6. Pin 2 allows use of an external resistor to ground for
optional, higher current. For 20 mA operation, no resistor is
used.
For IDD ~ 40 mA, R2 = 43 ohms;
IDD ~ 60 mA, R2 = 15 ohms;
IDD ~ 80 mA, R2 = 10 ohms.
