Description
R8A66166SP is a LED array driver with a 16-bit serial input and parallel output shift register function, as well as a direct-coupled reset input and output latch function. It guarantees an output current of 24mA (Vcc = 5V case), making it suitable for cathode common LED drive. The parallel output is an open-drain output. This product is designed in complete CMOS, resulting in significantly reduced power consumption compared to conventional bipolar or Bi-CMOS products. The pin layout is designed for easy printed circuit implementation. R8A66166SP is the successor to the M66310 model.
Specifications and features
- Cathode common LED drive
- VCC 5V 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°C, 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: -40°C to +85°C
- Pin layout facilitates printed circuit wiring, cascade connection, and LED connection
Application Scenarios
R8A66166SP is suitable for various LED display modules, LED array drives, as well as PPC, printers, VCRs, Mini-compos, button telephones, and other LED display equipment.
