I accidentally came across a long-discontinued NE555N timer on sale. The price is terribly high, but they are sold in a very old and respected store in my city. I decided to buy for the sake of interest. Please tell me how to recognize a counterfeit? Does STM have any font typeface standards? Thanks in advance for the answers :)
By the way, the same question is about microcontrollers - many different boards have already accumulated and all of them are of different types: somewhere the case is rough, somewhere smooth, fonts are similar but slightly different, font cut depth is also different.
