Is there a 7-segment LED driver IC that will do 0-F, preferably with a latch? Every chip I find is BCD and only does 0-9.
TIA!

Maxim, maybe. I've gone over to the STP16cp05 serial constant current led driver, quite nice, easy to drive once you get the look up table written

I almost hate to say it, but it would be cheaper to use a PIC these days. $2 or less, after the (small) software NRE of course. Much better long term availability too.

And you could talk to them via i2c to boot. Looks like the route I'm going to end up taking, thanks!

These puppies are twenty bucks apiece:

One place I worked at used these when they were only about ten bucks, and uPs still cost more than that. :-)

By the late '80s I'd already switched to 32x8 PROMs for such purposes (they were still cheaper than PALs, plus early on I didn't have any real programmers and used DIP switches to program the PROMs!)... I think I still have a couple of those boards around...
