Hi, I have a small stack (~60) of assorted "High-Noise-Immunity Logic" (HNIL or HINIL) chips that I have no use for, and would like to trade for something I do have a use for. These run off like +16V; numbers are 3xxCJ (for xx=03, 21, etc); they were made by Teledyne (the line was later bought out by ITT, whose part numbers for these are ITT3xx; also, at some point passed through Telcom, whose part #'s for the series are TSC3xx). If anyone's interested, let me know, I can send you a list of what I've got. Noel
