Description and Introduction

8-Digit, Microprocessor- Compatible, LED Display Decoder Driver The ICM7228CIJI is a 4-digit LED display driver manufactured by Maxim Integrated (formerly Intersil). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (formerly Intersil)  
- **Type:** 4-Digit LED Display Driver  
- **Interface:** Parallel  
- **Supply Voltage:** 4.5V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Pin PLCC (Plastic Leaded Chip Carrier)  
- **Digit Drive:** Common Cathode  
- **Segment Drive:** 8 segments (7 segments + decimal point)  
- **Multiplexing:** Yes (4-digit multiplexed display)  
- **Current Sink Capability:** 25mA per segment  

### **Descriptions:**
The ICM7228CIJI is a CMOS integrated circuit designed to drive 4-digit, 7-segment LED displays with multiplexing capability. It includes an on-chip BCD-to-7-segment decoder, digit drivers, and segment drivers, reducing the need for external components. It supports common cathode displays and is widely used in instrumentation, industrial control, and consumer electronics.

### **Features:**
- **Integrated BCD-to-7-Segment Decoder** – Simplifies interfacing with microcontrollers or logic circuits.  
- **Multiplexed Display Drive** – Reduces power consumption and component count.  
- **High-Sink Current Capability** – Supports bright LED displays with up to 25mA per segment.  
- **Wide Operating Voltage Range** – Compatible with 5V systems.  
- **On-Chip Digit and Segment Drivers** – Eliminates the need for external transistors.  
- **Low Power Consumption** – Suitable for battery-powered applications.  
- **PLCC Package** – Compact and suitable for surface-mount applications.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

8-Digit, Microprocessor- Compatible, LED Display Decoder Driver

Alternative Part Number

  • MAX7219CNG+ --: 8-digit LED display driver in DIP package, functionally similar to the ICM7228 display driver and widely available as a drop-in style replacement for multiplexed 7-segment displays.
  • MC14489BDWE --: Multiplexed 5-digit LED display driver with similar display-driving function and serial interface, suitable as an alternative display controller.
  • MM5450BN --: Serial-input LED display driver capable of driving multiple segments, commonly used as a substitute display driver in similar applications.
  • ICM7218CIJI --: Same ICM72xx display driver family from the original Harris/Intersil lineage, offering comparable 8-digit LED drive capability.
  • MC14489B --: Multiplexed LED display driver with similar segment-drive function, usable as a functional substitute in many display applications.
