Parameters are tested with production test circuit below (Fig 1).
Parameters are tested at ambient temperature with test limits guard-banded for specified operating temperature.
Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310.
Measured from 20% to 80% of a full output swing (Fig 2).
Not tested in production, guaranteed by design, verified at qualification.
Integrated across stated bandwidth per GR-253-CORE Issue3.
Tested with Vc = 0.3V to 3.0V unless otherwise stated in part description

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 datasheet. Exposure to absolute maximum ratings for extended periods may adversely affect device
reliability. Permanent damage is also possible if OD or Vc is applied before Vcc.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and
IR reflow simulation. The VS-720 family is capable of meeting the following qualification tests:
Environmental Compliance
Parameter
Mechanical Shock
Mechanical Vibration
Solderability
Gross and Fine Leak
Resistance to Solvents
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
Handling Precautions
Although ESD protection circuitry has been designed into the VS-720 proper precautions should be taken when
handling and mounting. VI employs a human body model (HBM) and a Man Man method (MM) for ESD
susceptibility testing and design protection evaluation.

Temperature (DegC)
The device 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. The VS-720 device is hermetically
