The MC14489B 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 MC14489B features data retention plus decode and scan circuitry, thus relieving processor overhead. A single, current-setting resistor is the only ancillary component required.
A single device can drive any one of the following: a 5-digit display plus decimals, a 4-1/2-digit display plus decimals and sign, or 25 lamps. A special technique allows driving 5 1/2 digits; see Figure 16.A configuration register allows the drive capability to be partitioned off to suit many additional applications.The on-chip decoder outputs 7-segment-format numerals 0 to 9, hexadecimal characters A to F, plus 15 letters and symbols.
The MC14489B is compatible with the Motorola SPI and National MICRO-WIRETM serial data ports.The chip's patented BitGrabberTM registers augment the serial interface by allowing random access without steering or address bits.A 24-bit transfer updates the display register. Changing the configuration register requires an 8-bit transfer.
● Operating Voltage Range of Drive Circuitry: 4.5 to 5.5 V
● Operating Junction Temperature Range: -40℃ to 130℃
● 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.)

I recently purchased the MC14489BPE integrated circuit from Utsource and I am very pleased with the product. The circuit was tested and found to be in perfect working order. The circuit was also packaged securely and arrived in a timely manner. I would highly recommend Utsource for any integrated circuit needs.
