MOTOROLA SEMICONDUCTOR TECHNICAL DATA
M u Iti-Character lED CMOS
The MC144898 is a flexible light-emitting-diode driver which directly interfaces to individual lamps, 7-segment displays, or various binations of both. LEOs wired with mon cathodes are driven in a multiplexed-by-5 fashion. munication 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 ponent required. A single device can drive anyone of the following: a 5-digit display plus decimals, a 4-112-digit display plus decimals...
