Description and Introduction

Dual 2-Line To 4-Line Decoders / Demultiplexers The SN74AHC139PWR is a dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Type:** Decoder/Demultiplexer  
- **Technology:** AHC (Advanced High-Speed CMOS)  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-16  
- **Number of Channels:** 2 (Dual)  
- **Input Type:** CMOS  
- **Output Type:** Push-Pull  
- **Propagation Delay:** 8.5 ns (typical at 5 V)  
- **Low Power Consumption:** 0.8 µA (maximum ICC)  
- **High Noise Immunity:** CMOS levels  

### **Descriptions:**  
The SN74AHC139PWR is a dual 2-to-4 line decoder/demultiplexer designed for high-speed CMOS applications. It accepts two binary-weighted inputs (A0, A1) and decodes them into four mutually exclusive outputs (Y0-Y3). Each decoder has an active-low enable input (E) that, when high, forces all outputs to a high state.  

### **Features:**  
- **Dual Decoder Configuration:** Contains two independent 2-to-4 decoders in a single package.  
- **Wide Operating Voltage:** Supports 2 V to 5.5 V, making it compatible with TTL and CMOS logic levels.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **High-Speed Operation:** Suitable for high-performance digital systems.  
- **Balanced Propagation Delays:** Ensures consistent timing performance.  
- **ESD Protection:** Exceeds 2000 V per JESD 22.  

This device is commonly used in memory addressing, data routing, and signal demultiplexing applications.
