So there's the common chips like 4511 and 7447 which will do 4-bit BCD to 7-segment display... But, that leaves out the other 6 binary combinations, which we commonly represent as A-F.
Is there a single-chip 7-segment decoder that will display the full range of 4-bit values, 0-F?
Also, does anyone make an SMD version of 7447? I couldn't find one.
Probably overkill but you could use a MAX7219 or MAX7221 which can drive any combination of segments across up to 8 digits from a single IC but they need a small amount of programming and use a serial interface rather than parallel BCD. They are available as SMD.
Note that several PICs are pin and 'almost' program compatible. The 628/628A may be more expensive than the 16F1826/1827/1847 which may be cheaper and are almost a drop in replacement.

Oh, I agree. It's only a few cents difference so strictly from cost standpoint probably not worth changing, but I would adapt it to one of the 14-pin PICs from the 16F family if I wanted to spend time on that.
