MAX6971 sink driver schematic?

I'm building a custom led display, which is already prototyped with an Ardiuno and working that uses multiple Maxim MAX6971ANG+MAX6971ANG+ sink drivers. Rather than trying to wire this mess myself, I decided to try building my own PCB. Since I've been designing chips for nearly 20 years, learning Eagle hasn't been to difficult, surprisingly fun, and I've already have much of the schematic drawn.

The problem is that I can't find a schematic for the 6971. Is there one available? Am I missing it? Do I need to draw one myself?

Thanks for your help.

If you find one you need to verify it is correct for your needs and
matches the data sheet. It takes about the same amount time to make a
symbol from scratch, find or make a package and then connect a device.

The advice is any part you use should be copied into "your lib" after it
is checked for correctness and use it from there.

Hi Bob

Not one available in the Eagle libraries but try the attached. It was a
simple adaption from a MAX7219EWGMAX7219EWG which was in MAXIM.lbr

As always when receiving a library item from another, verify the package
dimensions are correct and the pin / pad relationship is correct before
using it.
