6 Device Characteristics
6.1 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.
External leads can be bonded and soldered safely at temperatures of up to 220
°
C.
6.2 Handling Precautions
All MOS devices must be handled with certain precautions to avoid damage due to the accumulation of static
charge. Although input protection circuitry has been incorporated into the devices to minimize the effect of this
static buildup, proper precautions should be taken to avoid exposure to electrostatic discharge during handling and
mounting.
Agere
Systems Inc.
employs a human-body model for ESD-susceptibility testing. Since the failure volt-
age of electronic devices is dependent on the current, voltage, and hence, the resistance and capacitance, it is
important that standard values be employed to establish a reference by which to compare test data. Values of
100 pF and 1500
are the most common and are the values used in the
Agere
human-body model
test circuit.
The breakdown voltage for the DSP16410C is greater than 1000 V.
