Description and Introduction

12-Bit Asynchronous Binary Counters The SN74HC4040N is a 12-stage binary ripple counter manufactured by Texas Instruments.  

### **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:** PDIP-16  
- **Mounting Type:** Through Hole  
- **Output Type:** Standard  
- **Propagation Delay Time:** 20 ns (typical at 5V)  
- **High-Level Output Current:** -5.2 mA  
- **Low-Level Output Current:** 5.2 mA  
- **Reset Function:** Asynchronous Master Reset (active HIGH)  

### **Description:**  
The SN74HC4040N is a high-speed CMOS 12-bit ripple counter with an asynchronous master reset. It is designed for general-purpose counting applications and operates over a wide voltage range (2V to 6V). Each stage divides the frequency by 2, providing outputs for all 12 bits.  

### **Features:**  
- **12-Stage Binary Ripple Counter**  
- **Asynchronous Master Reset**  
- **High-Speed Operation** (typical propagation delay of 20 ns at 5V)  
- **Wide Operating Voltage Range** (2V to 6V)  
- **Low Power Consumption** (HC technology)  
- **Balanced Propagation Delays**  
- **Direct Interface with TTL Levels**  
- **Schmitt-Trigger Clock Input for Noise Immunity**  

This information is based on the manufacturer's datasheet and technical documentation.
