Proper ESD control techniques should be used when handling these devices. 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. 0 = TTL Low; 1 = TTL High 8. C1 is specified as the cont rol 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.
