Description and Introduction

10-LINE TO 4-LINE AND 8-LINE TO 3-LINE PRIORITY ENCODERS The SN54148/J is a priority encoder integrated circuit manufactured by Texas Instruments (TM).  

### **Specifications:**  
- **Function:** 8-line to 3-line priority encoder  
- **Logic Family:** TTL (Transistor-Transistor Logic)  
- **Operating Voltage:** 4.75V to 5.25V  
- **Operating Temperature Range:** -55°C to +125°C (Military-grade)  
- **Package Type:** Ceramic DIP (Dual In-line Package)  
- **Number of Pins:** 16  
- **Input Lines:** 8 active-low inputs (I0 to I7)  
- **Output Lines:** 3 binary-coded outputs (A0, A1, A2)  
- **Enable Input:** Active-low enable input (EI)  
- **Enable Output:** Active-low enable output (EO)  
- **Group Select Output:** Active-low group select (GS)  

### **Descriptions:**  
The SN54148/J is a high-speed priority encoder that converts 8 active-low inputs into a 3-bit binary-coded output. It features priority encoding, where the highest-order input (I7) has the highest priority. The device includes enable inputs and outputs for cascading multiple encoders.  

### **Features:**  
- **Priority Encoding:** Highest-order input takes precedence  
- **Cascading Capability:** Supports expansion using enable inputs/outputs  
- **High-Speed Operation:** Suitable for fast digital systems  
- **Military-Grade Reliability:** Designed for harsh environments  
- **TTL-Compatible Inputs/Outputs:** Works with standard TTL logic levels
