Description and Introduction

12-Bit Asynchronous Binary Counters The SN74LV4040APWR is a 12-bit binary ripple counter manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Category:** Counter/Divider  
- **Logic Type:** Binary Counter  
- **Number of Bits:** 12  
- **Trigger Type:** Negative Edge  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** TSSOP-16  
- **Mounting Type:** Surface Mount  
- **Output Type:** Standard  
- **Propagation Delay Time:** 16 ns (typical at 5 V)  
- **Reset:** Asynchronous Master Reset (active HIGH)  
- **Clock Frequency:** Up to 100 MHz (at 5 V)  

### **Descriptions:**  
The SN74LV4040APWR is a 12-bit ripple counter with an asynchronous master reset. It operates over a wide voltage range (2 V to 5.5 V), making it suitable for low-voltage applications. The counter advances on the HIGH-to-LOW transition of the clock input (CP). A HIGH level on the master reset (MR) clears all counter stages asynchronously.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **Low Power Consumption:** Optimized for battery-operated devices  
- **High-Speed Operation:** Up to 100 MHz at 5 V  
- **Asynchronous Reset:** Allows immediate clearing of the counter  
- **Schmitt-Trigger Clock Input:** Noise immunity for reliable counting  
- **Standard Outputs:** Compatible with TTL levels  
- **Small Package (TSSOP-16):** Space-saving for compact designs  

This information is strictly based on the manufacturer's datasheet and specifications.
