I *thought* it might be the case, but couldn't find any confirmation of it anywhere. I couldn't find any reference in the data sheets as to whether Rds(on) was the same as Rsd(on)... but I suppose the R part should have been a give-away, in hindsight. Thanks for the correction. Now that I've learned something I guess I can go home and call it a day! 8-) Dale -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
