I'm not affiliated with Arrow in any way, just saw these chips at a very good price and in stock, so I ordered some myself. I hope it will be helpful to somebody. If you want it - order now, as they will probably run out of stock really quickly. When I placed my order, there were 99 of them in stock, now only 71 is remaining.
