The M66503A is a constant current LED driver IC, whose output current is variable. The IC's functions include 16-bit
serial input/parallel output shift register with output latch.
The product uses Bi-CMOS process for highly accurate constant current driving, permitting high-efficiency LED driving
without using a resistor that limits LED current.
Settings for the LED drive current are made by an external resister,thereby ensuring a maximum output current of 30 mA,enough for anode-common LED driving.
Furthermore, the pin configuration of the IC permits easier wiring on a printed board.
