If you have ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The bidirectional logic level converter is a small device that safely steps down 5V signals to 3.3V and simultaneously steps up from 3.3V to 5V. This level converter also works with 2.8V and 1.8V devices. What really sets this Logic level converter apart from previous versions is that you can successfully set your high and low voltages and safely step up and down between them on the same channel.
