INPUT
GND terminal for control logic driver
Serial data input terminal for shift register
Clock input terminal for data shift to up−edge
"H" Level : data through, "L" Level : data hold
Supply voltage terminal
Output terminals
"H" Level output off, "L" Level : latch data = "H" Level then output on, latch data = "L" Level
then output off
Serial data output terminal for shift register
The register which connects between R−EXT and GND sets the constant output current.
