Description
The M66313FP is a semiconductor integrated circuit for LED array driver with 32-bit serial-input, parallel-output shift
register, equipped with direct set input and output latches.
The M66313FP guarantees sufficient 24 mA output current to drive anode common LED, allowing 32-bit simultaneous
and continuous current output.
The parallel outputs are open-drain outputs.
The M66313FP employs CMOS technology, allowing considerable reduction of power dissipation, compared to
previous BIPOLAR or Bi-CMOS products.
In addition, the pin configuration is suitable for easy wiring on the printed circuit board.
