DESCRIPTION
I/O
I
DS–link data input
O
DS–link data output
I
Clock input for gray scale. The gray scale display is accomplished by lighting the LED until the
number of the gray-scale clock counted is equal to the data latched.
–
Ground
Constant-current value setting. LED current is set to the desired value by connecting an external
I/O resistor between IREF and GND. The 168 times current compared to current across the external
resistor flows through the constant-current output terminals.
Constant-current output.

Power supply
Reset signal. This signal is used to initialize the device reset is accomplished by pulling this pin low
I
(internally pulled up with a 330-kΩ resistor). If not used, this terminal should be left open or connect
to VCC.
