Description and Introduction

Dual 2-Line To 4-Line Decoder/Demultiplexer The SN74LVC139ADBR is a dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Decoder/Demultiplexer  
- **Number of Channels:** 2  
- **Input Lines:** 2 (per decoder)  
- **Output Lines:** 4 (per decoder)  
- **Supply Voltage Range:** 1.65V to 3.6V  
- **High-Speed Operation:** tpd (propagation delay) ≈ 4.3 ns at 3.3V  
- **Low Power Consumption:** ICC (static current) ≈ 10 µA  
- **Input/Output Compatibility:** 5V tolerant inputs  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SSOP-16 (DBR)  

### **Descriptions and Features:**  
- **Dual Decoder/Demultiplexer:** Contains two independent 2-to-4 decoders in a single package.  
- **Active-Low Outputs:** Each decoder has four inverted outputs.  
- **Enable Inputs:** Each decoder has an active-low enable (G) input for control.  
- **Wide Voltage Range:** Operates from 1.65V to 3.6V, making it suitable for low-voltage applications.  
- **5V-Tolerant Inputs:** Allows interfacing with 5V logic levels.  
- **Balanced Propagation Delays:** Ensures consistent timing performance.  
- **Low Noise:** Designed for reduced switching noise.  
- **Applications:** Used in memory decoding, data routing, and logic function generation.  

This information is based solely on the manufacturer's datasheet.
