Quick question, Why would you need a soft / slow rise time on the anode cut off to reduce switching noise when the cathodes are toggled repeatedly by the 74141? Surely that introduces just the same switching noise that would be produced with just a high side switching FET or BJT? Or does the 74141 feature a slow transition on its output? I can appreciate the optical isolation for the high side switching as being a nice part of the opto-couple solution though!
