Enable/Disable Functional Description
Under normal operation the Enable/Disable is left open, or set to a logic high state, and the VCC6 is an oscillation mode with active outputs. When the E/D is set to a logic low, the oscillator stops and the both the output and complementary output are in a high impedance state. This helps facilitate board testing and troubleshooting.
Absolute Ratings
Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not implied at these or any other conditions in excess of conditions represented in the operational sections of this data sheet. Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Table 5.

Reliability
The VCC6 qualification tests include the following:
Table 6. Environnemental Compliance
Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Moisture Sensitivity Level Conditions MIL-STD-883 Method 2002 MIL-STD-883 Method 2007 MIL-STD-883 Method 2003 MIL-STD-883 Method 1014 MIL-STD-883 Method 2016 MSL1
Handling Precautions
Although ESD protection circuitry has been designed into the the VCC6, proper precautions should be taken when handling and mounting. VI employs a Human Body Model and a Charged-Device Model (CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry wide standard has been adopted for the CDM, a standard HBM of resistance = 1.5kohms and capacitance = 100pF is widely used and therefore can be used for comparison purposes.

Suggested IR profile
Table 8 shows max temperatures and lower temperatures can also be used e.g. peak temperature of 220C. Termination finish is gold over nickel. The VCC6 is hermetically sealed so an aqueous wash is not an issue.
