R8A66162SP - 32-BIT LED DRIVER

General Description

The R8A66162SP 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.

Key Features

  • Anode common LED drive.
  • VCC 5V or 3.3V single power supply.
  • High output current: All parallel outputs Q1~Q32 IOL=24mA (at VCC=5.0V), IOL=12mA (at VCC=3.3V), LEDs can be turned on simultaneously.
  • Low power dissipation: 200uW/package (max) (VCC=5.0V, Ta=25OC, quiescent state).
  • High noise margin: Employment of Schmitt-trigger circuit on all inputs allows.

R8A66162SP 32-BIT LED DRIVER WITH SHIFT REGISTER AND LATCH REJ03F0263-0100 Rev. 1.00 Jan. 24. 2008 DESCRIPTION The R8A66162SP 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 R8A66162SP guarantees sufficient 24mA (Vcc=5.0V case) output current to drive anode common LED, allowing 32-bit simultaneous and continuous current output. The parallel outputs are open-drain outputs. In addition, as this product has been designed in complete CMOS, power consumption can be greatly reduced when compared with conventional BIPOLAR or Bi-CMOS products. Furthermore, pin layout ensures the realization of an easy printed circuit. R8A66162SP is the succession product of M66313FP. www.
