Description and Introduction

12-Bit Asynchronous Binary Counters The SN74HC4040DR is a 12-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:** 80 µA (max) at 5V  
- **Number of Stages:** 12  
- **Output Drive Capability:** 10 LSTTL Loads

- **Package Type:** SOIC (DR)  

### **Descriptions:**  
The SN74HC4040DR is a high-speed CMOS logic device that functions as a 12-bit binary ripple counter. It features a master reset (MR) input that asynchronously clears all counter stages when a high level is applied. The counter advances on the high-to-low transition of the clock (CP) input.  

### **Features:**  
- **12-Bit Binary Counter**  
- **Asynchronous Master Reset**  
- **Wide Operating Voltage Range (2V to 6V)**  
- **Balanced Propagation Delays**  
- **High Noise Immunity**  
- **Schmitt-Trigger Clock Input for Pulse Shaping**  
- **Compatible with LSTTL Logic Levels**  

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