OUTPUT
Ground terminal for logic and constant current control circuit
Serial data input terminal
Clock input for shift register. The data in shift register is shifted
synchronizing to the rising edge of CLK.
Latch input. When this terminal goes low, the data on shift register goes through the latch .
When this terminal goes high, the data is latched.
Constant current output terminal. This terminal is open collector output.
Ground terminal for LED driver.
Inpit foe output enable.
When XEN goes high, all outputs of constant current driver goes off.
When XEN goes low and data of latch (Ln) goes high, the corresponding
outputs (OUTn) of constant current driver turns on.
Serial data output
Control terminal of constant current value . Output current (IOUT) is set by connecting
one external resistor or one current source between R-EXTand GND.
Power supply for logic and constant current circuit
OUTn
resistor: IOUT[A] = (Vref / R-EXT resistor) × 200
current source: IOUT[A] = R-EXT current × 200
