Stress Ratings
Warning Stresses listed in the following table may be applied to devices one at a time without causing
permanent damage. Functionality at or exceeding the values listed is not implied. Exposure to these
values for extended periods may affect device reliability.
Warning This device can be damaged by electrostatic discharge (ESD) voltage. Microsemi
recommends that all integrated circuits be handled with appropriate precautions. Failure to observe
proper handling and installation procedures may adversely affect reliability of the device.
