How fast do you think I can update it, if I try it as fast as possible? Reply 2 years ago. Check the datasheets of your shift registers and other ICs to see what the maximum operating frequency is. Why is the output of the 3. Could it not be connected to 4794 8-stage shift-and-store register led Reply 4 years ago on Introduction. The matrix would pull to much current for the IC to handle. The column driver is drive only ONE column at any one time, so the current load should not be more than 8 4794 8-stage shift-and-store register led 15 mA or mA. It seems that one driver should suffice to drive any number of columns. Is this correct?
I recently saw this written up in EDN.
