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.

● 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 operating temperature range: Ta=-40oC~+85oC
● Pin layout facilitates printed circuit wiring. (This layout facilitates cascade connection and LED connection)
APPLICATION
● LED array drive, The various LED display modules
● PPC, Printer, VCR, Mini-compo, Button-Telephone etc. All of LED display equipment
