4 Electrical Characteristics
4.1 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.
Table 19. Absolute Maximum Ratings
4.2 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 employs a human-body model (HBM)
and charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation. ESD voltage
thresholds are dependent on the circuit parameters used in the defined 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:
