So I am trying to understand the datasheet for this seven segment display:
http://www.jameco.com/Jameco/Products/ProdDS/24740.pdf
I have an LSD3211
http://www.jameco.com/webapp/wcs/st...Id=10001&ddkey=http:StoreCatalogDrillDownView
On page 3 it states the forward current per chip for red is
40, 40 and 15 for SR, R and H respectively.
What do the SR, R and H stand for and what is the current level I should be targeting for this chip? 40 or 15 mA? I'm guessing 15 since 40mA seems awfully high for an led.
