- Freescale MC14489BDWE,  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 & scan circuitry,  thus relieving processor overhead. A single,  current -setting resistor is the only ancillary component required.
