hi,
im doing a project with a set of 12v strips leds.
im creating an led matrix from these, in a multiplex formation.
ive worked out that i need to use shift registers from my arduino to trigger the leds, but i know that the usual 74hc595 can't SINK the current, so ive plopped in there a direct replacement TPIC6B595, and this works fine.
but on my SOURCE line, i can't get my head around a replacement.
ive been pointed in the line of the 74HC595 with the ULN2803, or a TC4427, but both of these I'm having no luck.
is there a direct opposite for the TPIC6B595 in current SOURCE?
