Electrostatic Discharge (ESD) Protection Characteristics
Although damage from static discharge is much less common on these devices than on early CMOS
circuits, normal handling precautions should be used to avoid exposure to static discharge. Qualication
tests are performed to ensure that these devices can withstand exposure to reasonable levels of static
without suffering any permanent damage. All ESD testing is in conformity with CDF-AEC-Q00 Stress
Test Qualication for Automotive Grade Integrated Circuits. (http://www.aecouncil.com/) A device is
considered to have failed if, after exposure to ESD pulses, the device no longer meets the device
specication requirements. Complete dc parametric and functional testing is performed per the applicable
device data sheet at room temperature followed by hot temperature, unless specied otherwise in the
device data sheet.
