High voltage, high current Darlington arrays each containing seven open collector Darlington pairs with common emitters. Each channel rated at 500 mA and can withstand peak currents of 600 mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.

A great price on one if the most handy IC's you can have laying around. In fact, because it can be used at a fast enough switching speed to handle pwm signals, I build my arduino boards with one of these in line with 7 output pins, every time. Allows for control of my 12v projects. Heck, this are great just as stand alone relays for level shifting. No electronics kit should be without a handful of these darlington arrays.
I ordered these IC’s with a number of other electronic parts on 1-9-14. They were listed as “In Stock” so when they hadn’t arrived after a few days I tried tracking the order and discovered that while they were indeed “In Stock” the return on my query was “Delivery Estimate Wednesday, February 5, 2014 - Monday, February 24, 2014”. So I emailed Sunkee, the company shipping them, to find out why these items were taking so long. All my other items had arrived and these were holding up my project. They responded that they were in Hong Kong but that they shipped the order a week after I placed it and that “generally that take 2 weeks around arrival you”. I have since ordered and received like items on ebay so these will gather dust in the drawer when they arrive, whenever that will be. I don’t fault Sunkee from trying to make a living. I do fault Amazon for not providing the country of origin. Most people do...
Based on internet one would believe these can substitute for 7 darlington's. Disappointed they can't.
