7219 driver

I was thinking of adding opto-isolators and transistors to boost the
voltage/current of the MAX7219. I have had no experience with
opto-isolators and only minor experience with transistors in h-brdges. The
7219 sources the segments of the LEDs and sinks the digits of the LEDs.
Because of the multiplexing of the 7219 I assume speed is a big
consideration. I have an ideal what I need to do but was wondering if
someone more versed in these components could lend any advice, schematics?
Thanks, Dan
