MC14489 Datasheet Multi-character Led Display/lamp Driver

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC14489/D Multi-Character LED Display/Lamp Driver CMOS The MC14489 is a flexible light–emitting–diode driver which directly interfaces to individual lamps, 7–segment displays, or various binations of both. LEDs wired with mon cathodes are driven in a multiplexed–by–5 fashion. munication with an MCU/MPU is established through a synchronous serial port.

Key Features

  • data retention plus decode and scan circuitry, thus relieving processor overhead. A single, current.
  • setting resistor is the only ancillary component required. A single device can drive any one of the following: a 5.
  • digit display plus decimals, a 4.
  • 1/2.
  • digit display plus decimals and sign, or 25 lamps. A special technique allows driving 5 1/2 digits; see Figure 16. A configuration register allows the drive capability to be partitioned off to suit many additional ap.
