Product Summary
The MC144898 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 144898 features data retention plus decode and scan
circuitry, thus relieving processor overhead. A single, current-setting resistor
is the only ancillary component required.
