Description and Introduction

DUAL 4 BIT BINARY COUNTER The M74HC4520M1R is a dual 4-bit binary counter manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** STMicroelectronics  
- **Part Number:** M74HC4520M1R  
- **Logic Family:** HC (High-Speed CMOS)  
- **Type:** Dual 4-bit Binary Counter  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-16 (Small Outline, 16-pin)  
- **Propagation Delay:** Typically 20ns at 5V  
- **Output Current:** ±5.2mA  
- **Input Capacitance:** 3.5pF (typical)  
- **Power Dissipation:** 500mW  

### **Descriptions:**  
- The M74HC4520M1R consists of two identical 4-bit binary counters.  
- Each counter can be independently reset via a master reset (MR) input.  
- Counters can be cascaded for higher-bit counting applications.  
- Suitable for frequency division, time delay generation, and digital counting circuits.  

### **Features:**  
- **Dual Counter Design:** Two independent 4-bit counters in a single package.  
- **Synchronous Counting:** Clock inputs trigger counting on the rising edge.  
- **Asynchronous Master Reset (MR):** Resets all flip-flops to zero when activated.  
- **Wide Operating Voltage:** Supports 2V to 6V, making it compatible with TTL levels.  
- **High Noise Immunity:** Typical of HC logic family.  
- **Low Power Consumption:** CMOS technology ensures low static power dissipation.  

This information is strictly based on the manufacturer's datasheet. For detailed application notes or further specifications, refer to the official STMicroelectronics documentation.
