Yes, thank you gentlemen for the responses to my inquiry regarding the rare and esoteric 74142 decade counter/nixie driver IC. I have successfully built a fully operational clock using them. It was not easy nor practical. But it works. This clock uses (17) ICs. I am seeking the supposed ancient RCA application note which reportedly describes a clock design that utilizes these 74142 ICs. The very existence of this app. note is in and of itself somewhat of an urban legend. Am I chasing a ghost here?
But many will ask "why bother doing it?"..............To which I answer: "because it's cool" On Tuesday, January 7, 2025 at 11:41:04 AM UTC-5 gregebert wrote: > There was a T4142 TTL IC that has a binary counter and nixie driver in one > device; the Texas Instruments datasheet was published in 1972.
