Hi svoynick,
Yes, what I originally said is what I need. I want to be able to switch on/off all three colours in the tri-color LEDS. I want to be able to control the common anode.
To elaborate, my plan is to have 8 MOSFETs sourcing current and 8 TLC5947s sinking current. By multiplexing the MOSFETs I now have a 8196 LED matrix. Also, before you suggest I split it into eight 824 matrices, this will not work because it is a 3D matrix (888 [*3 for RGB]) and doing anything else would greatly complicate the lattice.
My plan should work, I just seeking some assistance in choosing the right transistors. In hindsight I should have elaborated in my OP, but my question was fairly specific and I’m not really looking for alternative solutions to my problem.
Thanks!
Mitch
