### **Descriptions:**  
The SN74LV4040ANSR is a 12-stage binary ripple counter with a clock input (CP), an asynchronous master reset (MR), and buffered outputs from each counter stage. It operates over a wide voltage range (2 V to 5.5 V), making it suitable for low-voltage applications.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **High-Speed Operation:** Up to 100 MHz at 5 V  
- **Low Power Consumption:** 20 µA (max ICC)  
- **Asynchronous Master Reset:** Clears all stages  
- **Schmitt-Trigger Clock Input:** Allows slow input transition  
- **Balanced Propagation Delays:** Ensures stable performance  
- **ESD Protection:** Exceeds 2000 V (HBM)  

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