Description and Introduction

12-Bit Asynchronous Binary Counters The SN74HC4040D is a 12-stage binary ripple counter manufactured by Texas Instruments (TI).  

### **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  
- **Mounting Type:** Surface Mount  
- **Output Type:** Standard  
- **Propagation Delay Time:** 16 ns (typical at 5V)  
- **High-Level Output Current:** -5.2 mA  
- **Low-Level Output Current:** 5.2 mA  
- **Trigger Type:** Negative Edge  

### **Descriptions:**  
The SN74HC4040D is a high-speed CMOS logic 12-bit ripple counter with a master reset function. It is designed for general-purpose counting applications and operates over a wide voltage range. Each negative-going transition on the clock input increments the counter. A high-level reset signal asynchronously clears all flip-flops.  

### **Features:**  
- **12-Bit Binary Ripple Counter**  
- **Asynchronous Master Reset**  
- **Wide Operating Voltage Range (2V to 6V)**  
- **High Noise Immunity**  
- **Low Power Consumption**  
- **Balanced Propagation Delays**  
- **Direct Interface with TTL Levels**  
- **Schmitt-Trigger Clock Input for Noise Immunity**

Application Scenarios & Design Considerations

12-Bit Asynchronous Binary Counters

Alternative Part Number

  • MC74HC4040ADG --: Pin-compatible 12-stage binary ripple counter in the same HC logic family, widely available and functionally equivalent to the SN74HC4040D.
  • CD74HC4040E --: Same manufacturer and identical HC4040 function, offering a direct functional match though in a different package style.
  • 74HC4040D,653 --: Standard 74HC4040 ripple counter from an alternate vendor with equivalent logic function and similar SO package, suitable as a second-source option.
