Description

The R8A66160SP is an LED array driver that comes with a 16-bit serial input and parallel output shift register function. It also features a direct-coupled reset input and output latch function. This product guarantees an output current of 24mA (Vcc = 5V case) which is sufficient for cathode common LED drive. It is capable of following 16-bits continuously at the same time. Parallel output is open drain output. This product has been designed in complete CMOS and power consumption can be greatly reduced when compared with conventional BIPOLAR or Bi-CMOS products. The pin layout ensures the realization of an easy printed circuit. It is also important to note that R8A66160 is the succession product of M66310.

Specifications and features

• Cathode common LED drive
• VCC5V or 3.3V single power supply
• High output current: all parallel outputs QA~QPIOH=-24mA (at VCC=5.0V) IOH=-12mA (at VCC=3.3V) simultaneous lighting available
• Low power dissipation: 100uW/package (max) (Vcc=5.0V, Ta=25 o C, quiescent state)
