(1)

Creepage and clearance requirements should be applied according to the specific equipment isolation standards of an application.

Care should be taken to maintain the creepage and clearance distance of a board design to ensure that the mounting pads of the

isolator on the printed-circuit board do not reduce this distance. Creepage and clearance on a printed-circuit board become equal

in certain cases. Techniques such as inserting grooves, ribs, or both on a printed circuit board are used to help increase these

specifications.

(2)

This coupler is suitable for safe electrical insulation (ISO772x) and basic electrical insulation (ISO7721B) only within the safety ratings.

Compliance with the safety ratings shall be ensured by means of suitable protective circuits.

(3)

Testing is carried out in air to determine the surge immunity of the package

(4)

Testing is carried out in oil to determine the intrinsic surge immunity of the isolation barrier.

(5)

Apparent charge is electrical discharge caused by a partial discharge (pd).

(6)

All pins on each side of the barrier tied together creating a two-pin device.
