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.

Reliability
The VCC6 qualification tests include the following:

Parameter Conditions
Mechanical Shock MIL-STD-883 Method 2002
Mechanical Vibration MIL-STD-883 Method 2007
Solderability MIL-STD-883 Method 2003

Resistance to Solvents MIL-STD-883 Method 2016
Moisture Sensitivity Level 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.

Model Minimum Conditions
Human Body Model 1000 MIL-STD-883 Method 3115
Charged Device Model 1000 JESD 22-C101
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.
