NOTE
Creepage and clearance requirements should be applied according to the specific
application isolation standards. Care should be taken to maintain these distances on a
board design to ensure that the mounting pads for the isolator do not reduce this distance.
Creepage and clearance on the printed-circuit board become equal in certain cases.
Techniques such as inserting grooves and/or ribs on the printed circuit board are used to
help increase these specifications.
