1) Not subject to production test; specified by design
2) Parameters describe the behaviour of the internal SCD circuit. Therefore only internal delay times are considered. In
application dead-/ delay times determined by application circuit (switching times of MOSFETs, adjusted dead time) have
to be considered as well.
