I'm after a high side (source) low impedance driver for driving 
multiplexed LEDs.  I'm after something like this (Allegro 6810)

   http://www.allegromicro.com/sf/6810/

.. but, a lower cost lower voltage source driver for 8 or more bits.

I'm planning on using someone's source driver with the ST 16C596 
constant current sink driver ..

   http://www.st.com/stonline/books/ascii/docs/10154.htm

Which has a fairly good price (but 12 week lead time!).

Just to complete the picture, I'm currently using the TI TPIC6c595 
sink driver ..

   http://focus.ti.com/docs/prod/folders/print/tpic6c595.html

.. and the Toshiba TB62710 constant current source driver. So clearly, 
I'm moving from common cathode to common anode LEDs, and haven't quite 
completed the picture.
