Description and Introduction

Dual 2-Line To 4-Line Decoders/Demultiplexers The SN74LV139ARGYR is a dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Low Power Consumption:** 20 µA (typical)  
- **High-Speed Operation:** 8.5 ns (max) at 5 V  
- **Input Voltage Levels:**  
  - 0.8 V (max) for LOW  
  - 2 V (min) for HIGH (at 5 V supply)  
- **Output Drive Capability:** ±12 mA at 5 V  
- **Operating Temperature Range:** -40°C to +125°C

### **Descriptions:**  
- The SN74LV139ARGYR contains two independent 2-to-4 decoders in a single package.  
- It accepts two binary-weighted inputs (A0, A1) and decodes them into four mutually exclusive outputs (Y0-Y3).  
- An active-low enable (G) input allows for demultiplexing applications.  

### **Features:**  
- **Dual Decoder/Demultiplexer:** Two independent 2-to-4 decoders in one IC.  
- **Wide Operating Voltage:** Supports 2 V to 5.5 V operation.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **High Noise Immunity:** CMOS technology ensures reliable performance.
