Yes, the 7I37/7I37T has 8 isolated MOSFET switches (no common pins). You can connect each switch to whatever voltage you like (within the 7I37 ratings). You can even switch AC loads by connecting a pair of switches in series. Note that the MOSFETS have intrinsic source-drain diodes so they will conduct if connected backwards. > > Thanks, > Eric > > > _________________________________________________________________ > Stay in touch when you're away with Windows Live Messenger. > http://www.windowslive.com/messenger/overview.html?ocid=TXT_TAGLM_WL_messenger2_072008 Peter Wallace Mesa Electronics (\__/) (='.'=) This is Bunny.
