Features:
The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using.
High voltage (5V for example) to the ¡HV¡¯ pin, low voltage (3.3V for example) to ¡LV¡¯, and ground from the system to the ¡GND¡¯pin.
For example: High voltage is 5V, low voltage is 3.3V
HV connect with 5V power supply
LV connect with 3.3V power supply
GND connect the power negative pole
LVx input/output 3.3V TTL
HVx input/output 5V TTL
Bi-Directional transform between LVx and TVx
