If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge can be. A bidirectional logic level translator is a small device that safely steps down a 5V signal to 3.3V while boosting 3.3V to 5V. This level shifter is also available for 2.8V and 1.8V devices. What sets this logic level translator apart from our previous versions is that you can successfully set high and low voltages and safely raise and lower them on the same channel. Each level shifter has the ability to convert 4 pins on the high side to 4 pins on the low side, with two inputs and two outputs for each side
Level shifters are very easy to use. The board needs to be powered by the two voltage sources (high voltage and low voltage) used by the system. High voltage (eg 5V) to “HV” pin, low voltage (eg 3.3V) to “LV”, ground from system to “GND” pin
