1. Absolute maximum continuous ratings are those maximum values beyond which damage to the device may occur. Exposure to these
conditions or conditions beyond those indicated may adversely affect device reliability. Functional operation at absolute-maximum-rated
conditions is not implied.
2. V

1. Operating junction temperature impacts device life time. Maximum continuous operating junction temperature should be selected according
to the application life time requirements (Refer to Application Note AN1545 for more information). The device AC and DC parameters are
specified up to 110
°
C junction temperature allowing the MPC9894 to be used in applications requiring industrial temperature range. It is
recommended that users of the MPC9894 employ thermal modeling analysis to assist in applying the junction temperature specifications to
their particular application.
