Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Handling Precautions
Electrostatic Discharge
CAUTION: This device is susceptible to damage as a result of electrostatic discharge (ESD). Take proper
precautions during both handling and testing. Follow guidelines such as EIA
*
Standard EIA625.
Agere Systems Inc. employs a human-body model (HBM) for ESD-susceptibility testing and protection-design eval-
uation. ESD voltage thresholds are dependent on the critical parameters used to define the model. A standard
HBM (resistance = 1.5 k
, capacitance = 100 pF) is widely used and, therefore, can be used for comparison pur-
poses. The HBM ESD withstand voltage established for the 269-type laser pump module is ±500 V.
