Hello! I suspect that those are, ah, counterfeit. The datasheet does not indicate DIP8 designs. They only came in TSOC6 (which is a surface mounted package.) and TO-92. Which is strange because the markings on the one you show look surprisingly close to any of the ones I have here, which are all in the TO-92 package. Sorry. For the TSOC6 package I did a long campaign with Dallas Semiconductor to go ahead and create them in a rarely used DIP6 package, rarely used because it was only used in the industry for one specific device and not directly in the field. They told me that it would too expensive to do so, and especially for only one customer. I pointed out that many people would be interested in them, especially hobbyists who didn't have access to the tools for using the surface mountable packaging. No takers. ----- Gregg C Levine [email protected] "This signature fought the Time Wars, time and again." ------------------------------------------------------------------------------ Everyone hates slow websites.
