MC14489 Description
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.
