ilium007:
I need output for up to 60 leds and I'm looking at building multiple shift register based circuits. Most of the shift registers, such as the TPIC6B595, I have found that are available locally in Australia are limited to a constant drain current of 100 - 150mA, short of 160mA.
The TPIC6B595 can sink 8*150mA = 1200mA.
