All the ones I can find so far seem to be either out of production or maybe overkill. I think the **broken link removed** can do what you want (but I've only take a quick look at the datasheet)--but if you need only one digit, the 40-pin count and ~$6/unit price (at DigiKey) might be a problem. Maybe a sample?

Would something like this work? It outputs '0' through '9', 'A', 'b', 'C', 'd', 'E', and 'F' characters.
This is pretty much a finished PIC project (except I think we might have added a pull-down resistor on the base of the 2nd transistor). The code is posted further down in the first page of the following thread;
There are 2 or 3 CMOS D/Ds that output hex. The older 9368 was another wonderful one and used constant current outputs so that you didn't need current limiting resistors. The TIL311, even back when they were more easily available, would usually set you back about $10 or more EACH!
Sorry. I suggested the PIC project as it's pretty much complete and thought perhaps some kind soul near the OPs location might be able to 'burn' him a one-off '628A to send to him.
No I didn't. I'm not familiar with this particular component and I was simply interested in looking at the data sheet. I would have no way of knowing that a CD4495 is the same device, which by the way doesn't show up in a part number search on Mouser either...
Just a note on the 16F628A version. The PICs have about 65ohms resistance on when driving an output pin. You could skip the resistors as the displays would only get about 29ma per segment (assuming Red displays), plus you're muxing them so they should be just fine, bright too.
