Description and Introduction

12-Bit Asynchronous Binary Counters The SN74HC4040PWR is a 12-stage binary ripple counter manufactured by Texas Instruments. Here are its specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Maximum Clock Frequency:** 50 MHz (at 5V)  
- **Output Current:** ±5.2 mA (at 4.5V)  
- **Package Type:** TSSOP-16  
- **Propagation Delay:** 16 ns (typical at 5V)  

### **Descriptions:**
- The SN74HC4040PWR is a high-speed CMOS logic 12-bit binary counter.  
- It features a master reset (MR) input to clear all counter stages asynchronously.  
- The counter advances on the high-to-low transition of the clock (CP) input.  
- It is designed for general-purpose counting and frequency division applications.  

### **Features:**
- **12-Bit Binary Ripple Counter**  
- **Asynchronous Master Reset**  
- **Wide Operating Voltage Range (2V to 6V)**  
- **Low Power Consumption (HC Technology)**  
- **High Noise Immunity**  
- **Schmitt-Trigger Clock Input for Improved Noise Rejection**  
- **TSSOP-16 Package for Space-Saving Applications**
