Hi
I need to address individually like about 400 Led individually and in random at choice, for which I have made a matrix and multiplexing them as in sourcing the 20 columns and sinking the 20 rows.
Please advise which combo would be best?

1- Sourcing = 4017 , Sinking 4017?
2- Sourcing = 4017 , Sinking 74HC595?
3- Sourcing = 4510 , Sinking 4511?

or what else?

thanks
 
Like turning the LED,s on one at a time, from what I'm reading it seems it may rather be charlieplexing than multiplexing?
Actually they will be Optocouplers but same thing I guess?

just need to know what is the best choice of IC,s for sourcing and sinking LED,s when you only need to light them one at a time at choice? that's all.
