Handling Precautions
Although protection circuitry has been designed into this
device, proper precautions should be taken to avoid
exposure to electrostatic discharge (ESD) during
handling and mounting. EXAR 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 standard has been adopted for the CDM.
However, a standard HBM (resistance = 1500,
capacitance = 100 pF) is widely used and, therefore, can
be used for comparison purposes. The HBM ESD
threshold presented here was obtained by using these
circuit parameters:
