1) Not subject to production test; specified by design

2)

Parameters describe the behavior 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.
