Here is where my electronics noobishness comes in. I understand (kinda) how to do a high side PNP switch, but what transistor can switch 320mA (16 LEDs @ 20mA)? Or should I be looking at MOSFET's or maybe Darlington arrays?Yes, you could drive the anodes via high side PNPs. So 4*4 is 16 cathodes plus 4 anodes can fit on two 12 bit shift registers.
