Description and Introduction

14-Bit Asynchronous Binary Counters The SN74HC4020 is a 14-bit binary ripple counter manufactured by Texas Instruments (MOT is not the manufacturer).  

### **Specifications:**  
- **Logic Type:** Asynchronous Binary Ripple Counter  
- **Number of Bits:** 14  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Output Current:** -5.2 mA  
- **Low-Level Output Current:** 5.2 mA  
- **Propagation Delay:** 24 ns (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **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  

For accurate details, always refer to the official Texas Instruments datasheet.

Application Scenarios & Design Considerations

14-Bit Asynchronous Binary Counters

Alternative Part Number

  • CD74HC4020E --: Same 14-stage binary ripple counter function in the HC family, different CD prefix series, direct functional and pin-compatible replacement.
  • MC74HC4020ADG --: Equivalent 14-stage ripple counter with HC logic levels from a different manufacturer and MC prefix series, suitable drop-in alternative.
  • 74HC4020N --: Standard 74HC 14-stage binary counter with matching function and pinout, offered under a different vendor and naming convention.
  • MC74HC4020AN --: 74HC-series 14-stage ripple counter from a different vendor, same logic function and HC speed/power characteristics.
