1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
2. Figure 1 defines these parameters. Figure 2 illustrates the operating conditions under which
these parameters are tested and specified.
3. Symmetry is defined as Vs, On Time/Period.
4. Includes calibration tolerance, operating temperature, supply voltage variations, aging (10 years @ 40 degreesC) and shock
and vibration (not under operation).
5. Output will be enabled if enable/disable is left open.
6. Jitter is measured using a LeCroy8600 sampling 50,000 cycles.

Absolute Maximum 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.

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
The VCC6 has been qualified to meet the JEDEC standard for Pb-Free assembly. The temperatures and
time intervals listed are based on the Pb-Free small body requirements and parameters are listed in Table 5.
The VCC6 is hermetically sealed so an aqueous wash is not an issue.
