T7121 HDLC Interface for ISDN (HIFI-64)
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. Lucent 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:
