Description and Introduction

4 Digit (LED) Presettable Up/Down Counter The ICM7217BIJI is a 4-digit LED display driver manufactured by Maxim Integrated.  

### **Specifications:**  
- **Function:** 4-digit, 7-segment LED display driver  
- **Interface:** Parallel or serial (SPI compatible)  
- **Digits:** 4 (with multiplexed outputs)  
- **Segments:** 7 segments plus decimal point per digit  
- **Supply Voltage:** 4.5V to 6V  
- **Current Consumption:** Low power (typical 1mA in operation)  
- **Output Current:** Up to 25mA per segment  
- **Operating Temperature:** -40°C to +85°C  
- **Package:** 28-pin PLCC  

### **Descriptions and Features:**  
- **Multiplexed Display Drive:** Reduces external component count by multiplexing digit and segment signals.  
- **Flexible Input Modes:** Supports both parallel and serial data input for microcontroller interfacing.  
- **On-Chip Memory:** Includes digit latches to store display data.  
- **Brightness Control:** Adjustable via external resistor or PWM dimming.  
- **Decoding Capability:** Built-in BCD-to-7-segment decoder for simplified input.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **SPI Compatibility:** Allows easy integration with microcontrollers.  

This IC is commonly used in digital panel meters, instrumentation, and other applications requiring numeric LED displays.

Description and Introduction

4 Digit (LED) Presettable Up/Down Counter The ICM7217BIJI is a 4-digit LED display driver manufactured by INTERSIL.  

### **Specifications:**  
- **Supply Voltage:** 4.5V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Display Type:** Drives 7-segment LED displays (common cathode)  
- **Digits:** 4-digit multiplexed display  
- **Interface:** Serial or parallel data input  
- **Package:** 28-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The ICM7217BIJI is a CMOS integrated circuit designed to drive 4-digit LED displays with multiplexing capability.  
- It includes an on-chip oscillator for multiplex timing and supports both serial and parallel data input modes.  
- The device features a BCD-to-7-segment decoder and can be used in applications requiring numeric display control.  

### **Features:**  
- **Multiplexed Display:** Reduces external component count by driving digits sequentially.  
- **BCD Input:** Accepts Binary-Coded Decimal (BCD) data for direct 7-segment decoding.  
- **Serial/Parallel Data Input:** Flexible interfacing options.  
- **On-Chip Oscillator:** Eliminates the need for an external clock.  
- **High Output Drive:** Capable of driving common cathode LED displays directly.  
- **Low Power Consumption:** CMOS technology ensures efficient operation.  

This information is based strictly on the manufacturer's datasheet for the ICM7217BIJI.
