3 Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute
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.
3.1 Handling Precautions
Although electrostatic discharge (ESD) protection circuitry has been designed into this device, proper precautions must be
taken to avoid exposure to ESD and electrical overstress (EOS) during all handling, assembly, and test operations. Agere
employs both a human-body model (HBM) and a charged-device model (CDM) qualification requirement in order to
determine ESD-susceptibility limits and protection design evaluation. ESD voltage thresholds are dependent on the circuit
parameters used in each of the models, as defined by JEDEC’s JESD22-A114 (HBM) and JESD22-C101 (CDM)
standards.
3.2 Thermal Parameters (Definitions and Values)
System and circuit board level performance depends not only on device electrical characteristics, but also on device thermal
characteristics. The thermal characteristics frequently determine the limits of circuit board or system performance, and they
can be a major cost adder or cost avoidance factor. When the die temperature is kept below 125 °C, temperature activated
failure mechanisms are minimized. The thermal parameters that Agere provides for its packages help the chip and system
designer choose the best package for their applications, including allowing the system designer to thermally design and in-
tegrate their systems.
It should be noted that all the parameters listed below are affected, to varying degrees, by package design (including paddle
size) and choice of materials, the amount of copper in the test board or system board, and system airflow.
Θ
ΘJA - Junction to Air Thermal Resistance
ΘJA is a number used to express the thermal performance of a part under JEDEC standard natural convection conditions.
ΘJA is calculated using the following formula:
ΘJA = (TJ – Tamb) / P; where P = power
