MC14489 Product details

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 combinations of both.LEDs wired with common cathodes are driven in a multiplexed–by–5 fashion. Communication with an MCU/MPU is established through a synchronous serial port. The MC14489 features data retention plus decode and scan circuitry, thus relieving processor overhead. A single, current–setting resistor is the only ancillary component required.



• Operating Voltage Range of Drive Circuitry: 4.5 to 6 V

• Operating Junction Temperature Range: – 40°to 130°C

• Current Sources Controlled by Single Resistor Provide Anode Drive

• Low–Resistance FET Switches Provide Direct Common Cathode Interface

• Low–Power Mode (Extinguishes the LEDs) and Brightness Controlled via Serial Port

• Special Circuitry Minimizes EMI when Display is Driven and Eliminates EMI in Low–Power Mode

• Power–On Reset (POR) Blanks the Display on Power–Up, Independent of Supply Ramp Up Time

• May Be Used with Double–Heterojunction LEDs for Optimum Efficiency

• Chip Complexity: 4300 Elements (FETs, Resistors, Capacitors, etc.)

• See Application Note AN431, Temperature Measurement and Display Using the MC68HC05B4 and the MC14489and Engineering Bulletin EB153, Driving a Seven–Segment Display with the NEURONCHIP

About Motorola, Inc


Motorola, Inc. was an American multinational telecommunications company that was founded in 1928. It was headquartered in Schaumburg, Illinois and was one of the largest providers of mobile phones, telecommunication equipment, and semiconductors. Throughout its history, Motorola was known for its innovation in the field of telecommunications, including the development of the world's first commercially available cellular telephone, the DynaTAC, and the world's first two-way pager, the Pageboy.

In 2011, Motorola split into two separate companies: Motorola Mobility and Motorola Solutions. Motorola Mobility was later acquired by Google in 2012, and is now a subsidiary of Lenovo. Motorola Solutions focuses on public safety and commercial and industrial communication solutions. The company provides a wide range of products including two-way radios, mobile computing devices, and network infrastructure equipment.
