Description and Introduction

14-Bit Asynchronous Binary Counters The SN74HC4020 is a high-speed CMOS 14-stage binary ripple counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 2V to 6V  
- **High-Speed Operation:** 50 MHz (typical) at 5V  
- **Low Power Consumption:** 4 μA (max) at 5V  
- **Output Drive Capability:** 10 LSTTL Loads  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Options:** PDIP, SOIC, TSSOP  

### **Description:**  
The SN74HC4020 is a 14-stage binary ripple counter with a built-in oscillator. It features a master reset (MR) input to clear the counter asynchronously. The counter advances on the falling edge of the clock input (CP0).  

### **Features:**  
- **14-Stage Binary Counter**  
- **Asynchronous Master Reset**  
- **Schmitt-Trigger Clock Input for Noise Immunity**  
- **Balanced Propagation Delays**  
- **Direct LSTTL Input Compatibility**  
- **CMOS Input Compatibility**  

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

- **Package Options:** PDIP, SOIC, TSSOP  

### **Descriptions:**  
The SN74HC4020 is a high-speed CMOS logic device that functions as a 14-stage binary counter. It features a master reset (MR) input to clear the counter asynchronously. The counter advances on the falling edge of the clock input.  

### **Features:**  
- **Asynchronous Master Reset (MR):** Clears all flip-flops  
- **Wide Operating Voltage Range:** 2V to 6V  
- **Low Power Consumption:** CMOS technology  
- **High Noise Immunity:** Standard CMOS inputs  
- **Buffered Outputs:** Improved signal integrity
