Description and Introduction

DUAL 2-LINE TO 4-LINE DECODERS/DEMULTIPLEXERS The SN54HCT139J is a dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** HCT  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Type:** CDIP (Ceramic Dual In-Line Package)  
- **Number of Channels:** 2 (Dual Decoder)  
- **Input Type:** CMOS/TTL Compatible  
- **Output Type:** Push-Pull  
- **Propagation Delay:** Typically 23 ns at 5V  
- **Power Dissipation:** Low power consumption  

### **Descriptions and Features:**  
- Decodes two binary inputs (A0, A1) into four mutually exclusive outputs (Y0-Y3).  
- Active-LOW outputs, meaning only the selected output goes LOW while others remain HIGH.  
- Contains two independent 2-to-4 decoders in a single package.  
- Can be used as a demultiplexer by utilizing the enable (G) input.  
- High noise immunity due to CMOS technology.  
- TTL-compatible inputs for interfacing with TTL logic.  
- Designed for high-reliability applications, including military and aerospace.  

This device is part of TI’s high-speed CMOS (HCT) logic family, ensuring robust performance in harsh environments.
