Supply (VCC) Transients

These devices have a certain immunity to fast negative

going transients. The graph titled “Transient Rejection”

shows the maximum allowable transient amplitude and

duration to avoid triggering an unintended reset. As

shown in the graph shorter transients can have larger

amplitudes without triggering resets.
