I've never used that part. I have a few 68hc912b32 flash-based parts though and they have tremendous IO for a little 80 pin part. But yeah, there are serial input high and low side drivers as well.

This is a little 8-pin part :). I wanted something I could solder on vector board, as opposed to something I'd need to fabricate a printed circuit board for. Very small amount of ROM, no RAM (just registers). Still surprisingly handy. Designed to be used (in a pinch) with no auxiliary components at all.

Drivers I'm considering are your standard 7000-series shift registers. They should be able to source and sink enough current on each pin for an acceptable display. If not, I'd add a transistor for sinking on each row.

All of this is academic, of course, until my thesis is out of the way (doing a good job of eating my life so far).
