All Broadcom data sheets report the creepage and clearance inherent to the optocoupler component itself. These dimensions are needed as a starting point

for the equipment designer when determining the circuit insulation requirements. However, once mounted on a printed circuit board, minimum creepage

and clearance requirements must be met as specified for individual equipment standards. For creepage, the shortest distance path along the surface of a

printed circuit board between the solder fillets of the input and output leads must be considered (the recommended Land Pattern does not necessarily meet

the minimum creepage of the device). There are recommended techniques such as grooves and ribs which may be used on a printed circuit board to achieve

desired creepage and clearances. Creepage and clearance distances will also change depending on factors such as pollution degree and insulation level.
