7. 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.

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.
