Description and Introduction

Dual 2-Line To 4-Line Decoders/Demultiplexers The SNJ54HC139FK is a dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Technology Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Package Type:** FK (Flatpack)  
- **Number of Channels:** 2 (Dual Decoder)  
- **Input Type:** CMOS  
- **Output Type:** CMOS  
- **Propagation Delay Time:** Typically 13 ns at 5V  
- **Low Power Consumption:** 20 µA (Max)  
- **High Noise Immunity:** CMOS Technology  

### **Descriptions:**
- The SNJ54HC139FK is a high-speed CMOS logic device that decodes two binary inputs into four mutually exclusive outputs.  
- It can also function as a demultiplexer by using one of the inputs as a data line.  
- Designed for military and aerospace applications due to its ruggedized packaging and extended temperature range.  

### **Features:**
- **Dual 2-to-4 Line Decoder/Demultiplexer**  
- **Active-Low Outputs**  
- **Wide Operating Voltage Range (2V to 6V)**
