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 is applied before Vcc.

LV-PECL to LV-PECL: For short transmission lengths, the power  
consumption could be reduced by removing the 100resistor and  
doubling the value of the pull down resistors.  
LV-PECL to LVDS: Restricted for short transmission lengths.  
Configuration may require modification depending on LVDS receiver.

Functional Test: Allows standard power supply configuration.  
Since AC coupled, the LV-PECL levels cannot be measured.  
Production Test: Allows direct DC coupling into 50measurement  
equipment. Must bias the power supplys as shown. Similar to Figure 1.

Reliability  
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and  
IR reflow simulation. The SO-720 family is capable of meeting the following qualification tests:  
Environmental Compliance  
Parameter  
Mechanical Shock  
Mechanical Vibration  
Solderability  
Conditions  
MIL-STD-883, Method 2002  
MIL-STD-883, Method 2007

MIL-STD-883, Method 1014  
MIL-STD-883, Method 2016  
Gross and Fine Leak  
Resistance to Solvents  
Handling Precautions  
Although ESD protection circuitry has been designed into the SO-720 proper precautions should be taken when  
handling and mounting. VI employs a Human Body model (HBM) and a Man-Man model (MM) for ESD  
susceptibility testing and design protection evaluation.

The device is designed 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 SO-720 device is hermetically  
sealed so an aqueous wash is not an issue.
