Supply Transients
These devices have a certain immunity to fast negative
going transients. In the following pages the graph titled
“Glitch Rejection” indicates the maximum allowable glitch
amplitude and duration to avoid triggering an unintended
reset. As shown in the graph shorter transients can have
larger amplitudes without triggering resets.
