They're hex tri-state buffers -- the 8T97 is non-inverting and the 8T98 is inverting. I don't know if you can still get them or not, but you might have better luck looking for 8097 and 8098 which are equivalents from another manufacturer. I have pin-outs and specs if that would be of any use and I may even have some in the old junk box, but I'd have to look. ---- Larry Jones UUCP: uunet!sdrc!scjones SDRC scjones@sdrc.UU.NET 2000 Eastman Dr. BIX: ltl Milford, OH 45150 AT&T: (513) 576-2070 "When all else fails, read the directions."
