DESCRIPTION

TThe 1600 series are dual or quad isolation

transformer packs for use in digital circuits.

They are particularly suited to isolating

microprocessor bus connections and

performing logic level translation.

Being completely passive, power savings

are offered over opto-coupled or emitter

follower solutions.
