GTL logic? Thats a new one to me, yet it doesn't look as if its all that new if the onsies price is less than a pound. I clicked on the technical details link and got another copy of that page, so that was not "educational". I once used some level translators from Mitek, sounded tough from the spec sheet but turned out to be destroyable by the emp of a lighting strike half a mile away with an effective antenna length of about 8 feet. Very thin gated cmos stuff, no protection diodes at all. I had to redesign that board for another part. NXP is apparently the maker, and if you don't fill out the questionaire that asks waaay too many questions because theres always a page 7 to those things, they won't let you look at anything. If they have something, they should be bragging about it instead of using it for a data collection they'll sell the damned spammers. Screw `em, and the camel that rode in on them. :( Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
