NXP MC14489BDWE Multi‑Character LED Display Driver 20‑SOIC

The NXP MC14489BDWE is a versatile, 5-channel LED driver expertly designed for applications that demand efficient control of multi-digit 7-segment displays or lamp arrays. Its SOIC-20 surface-mount package (12.95 × 7.6 × 2.4 mm) offers a compact footprint for space-conscious designs. Moreover, this robust driver simplifies display management by using a single current-setting resistor, integrated decode and scan logic, and data retention, significantly reducing microcontroller overhead. Communication occurs via a synchronous serial interface compatible with SPI and National MICRO‑WIRE protocols.

Product Standout Features and Benefits

• Flexible Output Handling: Capable of driving a 5‑digit display plus decimals, 4½‑digit with sign, or up to 25 lamps. Multiplexed‑by‑5 architecture enhances signal control flexibility.
• Brightness & Power Control: Includes low-power mode to extinguish LEDs, brightness adjustment via serial port, and power-on-reset (POR) to blank the display at startup, ensuring visual clarity.
• Low EMI Operation: Built‑in circuitry minimizes electromagnetic interference during operation and in low‑power mode.
• Wide Operating Temperature: Rated from −40 °C to +130 °C, suitable for industrial and automotive environments.
• Automotive-Grade Qualification: Meets AEC‑Q100 standards for reliability in demanding applications.
