Description and Introduction

10-LINE TO 4-LINE AND 8-LINE TO 3-LINE PRIORITY ENCODERS The SN54147J is a 10-line to 4-line priority encoder manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Logic Type:** Priority Encoder  
- **Number of Input Lines:** 10 (active-low)  
- **Number of Output Lines:** 4 (active-low binary code)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C (Military grade)  
- **Package Type:** Ceramic DIP (Dual In-line Package)  
- **Technology:** TTL (Transistor-Transistor Logic)  

### **Descriptions:**  
- The SN54147J encodes 10 active-low inputs (9̅ to 0̅) into a 4-bit binary output (A̅3 to A̅0).  
- It implements priority encoding, where the highest-order input takes precedence if multiple inputs are active.  
- Designed for high-reliability military and industrial applications.  

### **Features:**  
- **Priority Encoding:** Highest-order input (9̅) has the highest priority.  
- **Active-Low Inputs/Outputs:** Inputs and outputs are active-low for compatibility with TTL logic.  
- **Wide Operating Temperature:** Suitable for harsh environments.  
- **High Noise Immunity:** Robust against electrical noise.  
- **TTL-Compatible:** Works with standard TTL logic levels.  

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