■ Functional Terminals/Setting Terminals

■ Application Example

ADR terminals

The ADRA terminal and ADRB terminal set device address A and device address B, respectively.

For “H” setting, connect the terminal to V

INV terminal

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.

RST terminal

When the voltage of the RST terminal becomes “L”, the internal circuit will be reset and the output will be open.
