MC14489B Multi-Character LED Display/Lamp Driver

Overview 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 synchro \n•Operating Voltage Range of Drive Circuitry: 4.5 to 5.5 V\n•Operating Junction Temperature Range: -40° to 130°C\n\n•Current Sources Controlled by Single Resistor Provide Anode Drive\n•Low-Resistance FET Switches Provide Direct Common Cathode Interface\n\n•Low-Power Mode (Extinguishes the LEDs) and;
