Description and Introduction

12-Bit Asynchronous Binary Counters The SN74HC4040 is a 12-stage binary ripple counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 2V to 6V  
- **High-Speed Operation:** Typical propagation delay of 13 ns at 5V  
- **Low Power Consumption:** 80 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 SN74HC4040 is a 12-bit ripple counter with a built-in oscillator. It features a master reset (MR) input that asynchronously clears all flip-flops. The counter advances on the high-to-low transition of the clock (CP) input.  

### **Features:**  
- 12-bit binary ripple counter  
- Asynchronous master reset  
- Buffered clock and reset inputs  
- Fully static operation  
- Wide operating voltage range  
- Balanced propagation delays  

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