MC14489BDWR2

Display Drivers Overview

The MC14489BDWR2 is a multi-character LED display and lamp driver manufactured by NXP USA Inc. It directly interfaces to individual lamps, 7-segment displays, or combinations thereof. The device drives LEDs wired with common cathodes in a multiplexed-by-5 fashion. Communication with a microcontroller or microprocessor is established through a synchronous serial port. The component features data retention plus decode and scan circuitry, relieving processor overhead. A single current-setting resistor is the only ancillary component required for operation.
