R8A66162SP
32-BIT LED DRIVER WITH SHIFT REGISTER AND LATCH
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.
FEATURES
● Anode common LED drive
● V
● High output current: All parallel outputs Q
● Low power dissipation: 200uW/package (max) (V
● High noise margin: Employment of Schmitt-trigger circuit on all inputs allows application with long wiring.
● Direct set input (S
● Open-drain output (Q
● Serial data output for cascading (SQ
● Wide operating temperature range (Ta=-40
● Pin configuration for easy layout on PCB. (Pin configuration allows easy cascade connection or LED
APPLICATION
● LED array drive, The various LED display modules
● PPC, Printer, VCR, Mini-compo, Button-Telephone etc. All of LED display equipments
