■ Functional Terminals/Setting Terminals
ADR terminals
INV terminal
RST terminal
The ADRA terminal and ADRB terminal set device address A and device address B, respectively.
For “H” setting, connect the terminal to V_DD and for “L” setting, connect the terminal to GND
This terminal sets the polarity of OUT terminal.
• When the terminal is used with “L” as active (e.g., for directly driving an LED), connect the terminal to V_DD
• When the terminal is used with the “H” as active (e.g., for driving an LED with a driving transistor), connect the terminal to GND.
When the voltage of the RST terminal becomes “L”, the internal circuit will be reset and the output will be open.
