I am looking for a MM5314N clock chip for a numitron clock project.
Does anyone know of a source for these chips?

If you don't mind buying from Europe...

i just saw two posted on ebay - Feb 2010 - wondering if you still have the tubes waiting for a chip.

Well, look at his user name... W8TZ => I read that as "WAITS". Since he never updated this thread, I was just helping him move on with his life.

It was funny, I saw it in ebay so I Googled it and this old thread was near the top of the list. Must be a dead chip if the best Google could do is this 3 1/2 year-old thread!

Indeed this chip is old. It was old when he asked about it. Interesting that somebody is selling some. I have various old chips I should sell.

You better sell your old chips if you don't need them or your family will in an estate sale. I picked up a box of about 500 chips/op amps/voltage regulators for $5 recently.
