1 All ESD testing is in conformity with CDF-AEC-Q100 Stress Test Qualification for
Automotive Grade Integrated Circuits.
2 A device is defined as a failure if after exposure to ESD pulses the device no longer
meets the device specification requirements. Complete DC parametric and functional
testing is performed per applicable device specification at room temperature followed by
hot temperature, unless specified otherwise in the device specification.
