Handling Precautions
Although protection circuitry has been designed into this device, proper precautions should be taken to avoid expo-
sure to electrostatic discharge (ESD) during handling and mounting. Agere Systems Inc. employs a human-body
model (HBM) and a charged-device model (CDM) for ESD susceptibility testing and protection design evaluation.
ESD voltage thresholds are dependent on the circuit parameters used to define the model. No industry-wide stan-
dard has been adopted for the CDM. A standard HBM (resistance = 1500
, capacitance = 100 pF) is widely
accepted and can be used for comparison. The HBM ESD threshold of >1000 V was obtained by using these cir-
cuit parameters:
