Description and Introduction

Dual 2-Line To 4-Line Decoders/Demultiplexers The SNJ54HC139J is a high-speed CMOS dual 2-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:**  
- **Logic Type:** Decoder/Demultiplexer  
- **Number of Bits:** 2  
- **Number of Input Lines:** 2  
- **Number of Output Lines:** 4 (per decoder)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Propagation Delay:** Typically 17 ns at 5V  
- **Input Current (Max):** ±1 µA  
- **Output Current (Max):** ±25 mA  
- **Package Type:** CDIP (Ceramic Dual In-Line Package)  
- **Package / Case:** 16-CDIP (0.300", 7.62mm)  
- **Mounting Type:** Through Hole  

### **Descriptions:**  
- The SNJ54HC139J is a dual 2-to-4 line decoder/demultiplexer designed for high-performance digital systems.  
- It features two independent decoders, each with two select inputs (A0, A1) and an active-low enable input (E).  
- When enabled, the selected output goes low based on the binary input combination.  
- It is part of the 54HC series, which is radiation-hardened and suitable for military and aerospace applications.  

### **Features:**  
- **High Noise Immunity:** CMOS technology ensures low power consumption and high noise margins.  
- **Wide Operating Voltage:** Supports 2V to 6V operation.  
- **Low Power Consumption:** Typically 20 µA quiescent current.  
- **Balanced Propagation Delays:** Ensures consistent performance.  
- **High Output Drive:** Capable of driving up to 10 LSTTL loads.  
- **Military Temperature Range:** Designed for harsh environments.  
- **Schmitt-Trigger Inputs:** Improves noise immunity on inputs.  

This information is strictly based on the manufacturer's datasheet and does not include any additional recommendations.
