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.

The V-Type family is capable of meeting the following qualification tests: Table 3. Environmental Compliance Parameter Conditions Mechanical Shock MIL-STD-883, Method 2002 Mechanical Vibration MIL-STD-883, Method 2007 Solderability MIL-STD-883, Method 2003 Gross and Fine Leak MIL-STD-883, Method 1014 Resistance to Solvents MIL-STD-883, Method 2015 Moisture Sensitivity Level MSL 1 Contact Pads Gold over Nickel Handling Precautions Although ESD protection circuitry has been designed into the V-Type proper precautions should be taken when handling and mounting. VI employs a human body model (HBM) and a charged device model (CDM) for ESD susceptibility testing and design protection evaluation. Table 4.
