DESCRIPTION

R8A66160 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 cathode common LED drive, capable of following 16-bits continuously atthe 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. R8A66160 is the succession product of M66310.

FEATURES
