The Bidirectional Logic Level Converter is a small device that safely drops a signal from 5V to 3.3V and rises from 3.3V to 5V The level converter is also suitable for 2.8V and 1.8V devices.
Each level shifter is capable of converting 4 pins on the high side to 4 pins on the low side and provides 2 inputs and 2 outputs for each side.
The level shifter needs to be powered by two voltage sources (HV and LV) used by the system. The high voltage (e.g. 5V) is connected to the "HV" pin, the low voltage (e.g. 3.3V) is connected to "LV" pin and the ground is connected from the system to the "GND" pin.
