I love this IC! I had run into a roadblock using a microcontroller to drive a relay board and was at a lose on how to remedy the problem. The relay board’s input was too much of a load for my microcontroller to handle. When I saw this IC demonstrated on YouTube I tried it and it worked perfectly the first time I wired it into my prototype.Highly recommended for interfacing microcontrollers to real world applications.DD
