### **Specifications:**  
- **Manufacturer:** INTERSIL  
- **Type:** 4-Digit LED Display Driver  
- **Interface:** Parallel  
- **Supply Voltage:** 4.5V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 40-Pin DIP (Dual In-Line Package)  
- **Display Type:** Drives Common Cathode LED Displays  
- **Multiplexing:** Yes (4-digit multiplexed display)  
- **Current Sinking Capability:** Up to 25mA per segment  
- **Features On-Chip:** BCD-to-7-segment decoder, digit drivers, segment drivers  

### **Descriptions:**  
The ICM7226AIJL is designed to drive 4-digit, 7-segment LED displays with multiplexing capability. It includes an on-chip BCD-to-7-segment decoder, eliminating the need for external decoding logic. The device supports parallel data input and is commonly used in instrumentation, digital panel meters, and other applications requiring numeric display control.  

### **Features:**  
- **Integrated Decoder:** Built-in BCD-to-7-segment decoder.  
- **Multiplexed Display Control:** Supports 4-digit multiplexing for reduced pin count.  
- **High Drive Capability:** Can sink up to 25mA per segment for bright LED display output.  
- **Wide Operating Voltage:** Works with a supply voltage of 4.5V to 6V.  
- **Common Cathode Support:** Designed for common cathode LED displays.

Application Scenarios & Design Considerations

TIMERS COUNTERS AND DISPLAY DRIVERS

Alternative Part Number

  • ICM7226BIJL --: Same ICM7226 series 8-digit counter/timer with a different grade suffix; pin-compatible and functionally equivalent, often a drop-in replacement when the A-grade is unavailable.
  • ICM7216BIJL --: Closely related Intersil 8-digit LED display driver/counter family member with similar pinout and function; usable as a functional substitute with minor feature differences.
  • MAX7219CWG --: Widely available 8-digit LED display driver from a different series; requires firmware/interface changes but serves as a practical alternative when the original ICM7226 is obsolete.
  • ICM7240IPE --: Intersil display driver/counter family device with comparable drive capability, suitable as a functional substitute where full feature match is not critical.
