Description and Introduction

12-Bit Asynchronous Binary Counters The SN74LV4040ADBR is a 12-bit binary ripple counter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Binary Counter  
- **Number of Bits:** 12  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High-Level Output Current:** -6 mA  
- **Low-Level Output Current:** 6 mA  
- **Propagation Delay Time:** 16 ns (typical at 5 V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SSOP (DBR)  
- **Package / Case:** SSOP-16  

### **Descriptions:**  
- The SN74LV4040ADBR is a 12-stage ripple counter with a clock input (CP) and an asynchronous master reset (MR).  
- It operates over a wide voltage range (2 V to 5.5 V), making it suitable for low-voltage applications.  
- The outputs change state synchronously on the high-to-low transition of the clock.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **Low Power Consumption:** Optimized for battery-operated devices  
- **Asynchronous Master Reset:** Clears all counter stages  
- **Schmitt-Trigger Clock Input:** Allows slow input transition and better noise immunity  
- **Balanced Propagation Delays:** Ensures stable operation  
- **SSOP Package:** Space-saving surface-mount design
