R8A66161SP - 16-BIT LED DRIVER

Download the R8A66161SP datasheet PDF. This datasheet also covers the R8A66161DD variant, as both devices belong to the same 16-bit led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

R8A66161 is a LED array driver having a 16-bit serial input and parallel output shift register function with direct coupled reset input and output latch function.

Key Features

  • Anode common LED drive.
  • VCC 5V or 3.3V single power supply.
  • High output current: all parallel outputs QA~ QP IOL=24mA (at VCC =5.0V) IOL=12mA (at VCC =3.3V) simultaneous lighting available.
  • Low power dissipation: 100uW/package (max) (VCC=5.0V, Ta=25 , quiescent state).
  • High noise margin: Schmitt input circuit provides responsiveness to a long line length.
  • Equipped with direct-coupled reset.
  • Open drain output: (except serial data output SQP).
  • Wide operati.

R8A66161DD/SP 16-BIT LED DRIVER WITH SHIFT REGISTER AND LATCH REJ03F0262-0100 Rev. 1.00 Jan. 16. 2008 DESCRIPTION R8A66161 is a LED array driver having a 16-bit serial input and parallel output shift register function with direct coupled reset input and output latch function. This product guarantees the output current of 24mA (Vcc =5V case) which is sufficient for anode common LED drive, capable of following 16-bits continuously at the same time. Parallel output is open drain output. 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. R8A66161 is the succession product of M66311. www.DataSheet4U.
