Handling Procedures Truth Table (Digital Attenuator) 8 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. C2 C1 Attenuation 0 0 Loss, Reference 0 1 16.0 dB 1 1 32.0 dB 0 = TTL Low; 1 = TTL High 8. C1 is specified as the control for the 16 dB bit. We show data for the performance with the C2 control - note that the power handling is reduced if C2 is used for the 16 dB bit. The electrical performance of the 16 dB bit controlled by C2 is not specified. 3 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 • Europe Tel: +353.21.244.6400 is considering for development.
