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 VVC4, 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.

The VVC4 is 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 the table
below. The contact pads are gold over nickel so lower IR reflow temperatures such as 220°C can be
used (device is backwards compatible with a lead solder assembly).
The VVC4 is hermetically sealed so an aqueous wash is not an issue.
