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
