Looking for best practices here. I'm building a common-anode LED matrix. I've got a current sink LED driver, and I'm looking for a latch that will provide enough current to drive an array of LEDs. All the latches I can find have very low current ratings. This guy had some success with running high current latches in parallel to provide the current, but it seems sloppy and is definitely expensive. I am leaning towards trying a low current latch with a Darlington array, however I've never used one before and don't know what exactly I'm looking for. Can anyone tell me if that's a good way to go about it, and suggest an 8 bit latch and Darlington array combo? Thanks.
