vintage IC data ...
Anybody got a sheet for a Texas Instruments TMS3874 digital clock IC ? Loads
of references on the 'net, and people claiming to be suppliers and having a datasheet, but you just finish up getting led down the path to companies in China, with no sign of the actual sheet ... Just the pin-out will do if nothing else available. It's a 'rescue' project for a very old mate, so not desperately important, but it would be nice to get it going for him again, as it was an apprentice piece that he built 38 years ago, and it has worked all that time until last week, when it just suddenly stopped. I'm loathe to believe that the IC itself has failed, but you never know ... Arfa |
