- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (16-pin)  

### **Descriptions:**  
- The SN74HC4020NSR is a high-speed CMOS logic device that functions as a 14-stage binary ripple counter.  
- It features a master reset (MR) input for synchronous clearing of all flip-flops.  
- The counter advances on the negative-going edge of the clock signal.  

### **Features:**  
- **14-Bit Binary Counter:** Provides a divide-by-16,384 output.  
- **Asynchronous Master Reset (MR):** Clears all stages when a high level is applied.  
- **Wide Operating Voltage Range:** 2V to 6V.  
- **High Noise Immunity:** Standard CMOS input levels.  
- **Balanced Propagation Delays:** Ensures reliable operation.  
- **Low Power Consumption:** Suitable for battery-powered applications.  

This device is commonly used in frequency division, time delay generation, and digital counting applications.
