Description and Introduction

12-Bit Asynchronous Binary Counters The SN74HC4040DWR is a 12-stage binary ripple counter manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Logic Type:** Binary Counter  
- **Number of Bits:** 12  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-16 (DWR)  
- **Output Type:** Standard  
- **Propagation Delay Time:** 24 ns (typical at 5V)  
- **High-Level Output Current:** -5.2 mA  
- **Low-Level Output Current:** 5.2 mA  
- **Mounting Type:** Surface Mount  

### **Descriptions and Features:**  
- **12-Stage Binary Counter:** Can count up to 4096 (2^12) states.  
- **Asynchronous Reset:** Includes a master reset (MR) input to clear the counter.  
- **High-Speed Operation:** Suitable for high-frequency applications.  
- **Wide Operating Voltage:** Supports 2V to 6V, making it compatible with various logic levels.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Standard Outputs:** Provides buffered outputs for improved signal integrity.  

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

Application Scenarios & Design Considerations

12-Bit Asynchronous Binary Counters

Alternative Part Number

  • MC74HC4040ADTR2G --: Same 12-stage binary ripple counter function in HC logic family, SOIC-16 wide body package, direct functional equivalent from a different manufacturer and series.
  • CD74HC4040M96 --: Equivalent 12-stage ripple counter in the CD74HC series, same HC logic and SOIC-16 package, pin-compatible alternative from a different TI series.
  • 74HC4040D,653 --: Standard 74HC4040 12-stage binary counter in SO16 package, functionally and pin compatible with the original device.
