Description and Introduction

Dual 2-Line To 4-Line Decoders/Demultiplexers The SNJ54S139J is a dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments (TM).  

### **Specifications:**  
- **Logic Type:** Decoder/Demultiplexer  
- **Number of Circuits:** 2  
- **Number of Input Lines:** 2 (per decoder)  
- **Number of Output Lines:** 4 (per decoder)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Type:** Ceramic DIP (Dual In-line Package)  
- **Technology:** Schottky TTL (S-Series)  

### **Descriptions and Features:**  
- The SNJ54S139J is designed for high-reliability military and aerospace applications.  
- It features two independent 2-to-4 decoders with active-low outputs.  
- Each decoder has two select inputs (A and B) and an active-low enable input (G).  
- The device can be used as a demultiplexer by using the enable input as a data input.  
- Schottky-clamped transistors ensure high-speed performance.  
- Low power consumption compared to standard TTL.  
- Designed for rugged environments with extended temperature and voltage ranges.  

This information is based on Texas Instruments' datasheet for the SNJ54S139J.

Description and Introduction

Dual 2-Line To 4-Line Decoders/Demultiplexers The SNJ54S139J is a dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology:** TTL (Transistor-Transistor Logic)  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C (Military grade)  
- **Package:** Ceramic Dual-In-Line (CDIP)  
- **Logic Family:** 54S (Schottky TTL)  
- **Number of Channels:** 2 (Dual decoder/demultiplexer)  
- **Input Type:** TTL-Compatible  
- **Output Type:** Active Low  

### **Descriptions and Features:**  
- **Function:** Decodes two binary inputs (A0, A1) into four mutually exclusive outputs (Y0-Y3).  
- **Demultiplexing Capability:** Can be used as a 1-to-4 demultiplexer when an enable input is used as the data line.  
- **Active-Low Outputs:** Outputs are low when selected.  
- **Enable Inputs:** Two enable inputs (G1, G2) for cascading and control.  
- **High-Speed Operation:** Schottky-clamped for improved switching speed.  
- **Military Qualified:** Meets MIL-PRF-38535 standards for high-reliability applications.  

This device is designed for high-speed decoding and demultiplexing in harsh environments, including aerospace and defense applications.
