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.

Features

• High output current.

All parallel output IOL = +24 mA, LEDs can be turned on simultaneously.

• Low power dissipation : 200 µW/package (max)

(VCC = 5 V, Ta = 25°C, quiescent state)

• High noise margin

Employment of Schmitt–trigger circuit on all inputs allows application with long wiring.

• Direct set input (SD)

• Open-drain output (Q1 to Q32)

• Serial data output for cascading (SQ32)

• Wide operating temperature range (Ta = −40 to +85°C)

• Pin configuration for easy layout on PCB.

(Pin configuration allows easy cascade connection or LED connection)

Application

LED array drive for eraser unit of a copying machine

LED array drive of a button telephone set

Various LED modules
