Freescale MC14489BDWE Linear IC MC14489B Multi-Character LED Display/Lamp Driver

The MC14489B is a flexible light-emitting-diode driver which directly interfaces to individual lamps, 7-segment displays, or various combinations of both. LEOs wired with common cathodes are driven in a multiplexed-by-5 fashion. Communication with an MCUIMPU is established through a synchronous serial port. The MC 14489B features data retention plus decode and scan circuitry, thus relieving processor overhead. A single, current -setting resistor is the only ancillary component required.
