Application Note S2083 is available on line at www.macom.com Handling Procedures Please observe the following precautions to avoid damage: Truth Table (Digital Attenuator)8 C2 0 0 1 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. C1 0 1 1 Attenuation Loss, Reference 16.0 dB 32.0 dB 0 = TTL Low; 1 = TTL High Moisture Sensitivity The MSL rating for this part is defined as Level 2 per IPC/JEDEC J-STD-020. Parts shall be stored and/or baked as required for MSL Level 2 parts. 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 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.
