    I used one of the Darlington arrays (ULN2003) to make a relay module and tested an OP-amp in my line following robot. Every IC I have used so far works great.

    I really happy that i am working with you
  • Ja***ck 
    GOOD!
  • Al***on 
    Just a lot of low-power diodes and diodes, but we need to check them tester to which I have not yet reached =), good packaging. 10 pieces of checked-call believable. waiting for the device to test and determine the characteristics but otherwise satisfied.
