Handling Precautions
CAUTION
:
This device is susceptible to damage as a result of electrostatic discharge. Take proper
precautions during both handling and testing. Follow guidelines such as JEDEC Publication
No. 108-A (Dec. 1988).
When handling and mounting line driver products, proper precautions should be taken to avoid exposure to electro-
static discharge (ESD). The user should adhere to the following basic rules for ESD control:
1. Assume that all electronic components are sensitive to ESD damage.
2. Never touch a sensitive component unless properly grounded.
3. Never transport, store, or handle sensitive components except in a static-safe environment.
ESD Failure Models
Lucent employs two models for ESD events that can cause device damage or failure:
1. A human-body model (HBM) that is used by most of the industry for ESD-susceptibility testing and protection-
design evaluation. ESD voltage thresholds are dependent on the critical parameters used to define the model. A
standard HBM (resistance = 1500
, capacitance = 100 pF) is widely used and, therefore, can be used for com-
parison purposes.
2. A charged-device model (CDM), which many believe is the better simulator of electronics manufacturing expo-
sure.
Tables 7 and 8 illustrate the role these two models play in the overall prevention of ESD damage. HBM ESD testing
is intended to simulate an ESD event from a charged person. The CDM ESD testing simulates charging and dis-
charging events that occur in production equipment and processes, e.g., an integrated circuit sliding down a ship-
ping tube.
The HBM ESD threshold voltage presented here was obtained by using these circuit parameters.
