The FETs are open drain, so do not drive a high voltage at > all, they just sink current. Afaik all the sink current goes through the PI when using that bidirectional converter. Therefore the slightly newer PI1541 hardware with unidirectional level converters is the recommendation. -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
