 		 #2670 - RE: interfacing a 7 segment display
Hi!

15 mA is a lot. A display from the stoneage...?

Get two 7 segment drivers (e.g. 74HCT4543) and connect them to the upper and lower nibble of the desired bus. These drivers contain latches. You only have to generate a latch enable signal (some neat adress decoder or a uC pin switched by software). Limit the LED current to 10 mA, that's what the ´4543 can handle per segment. Et voilá.
