Description and Introduction

Dual 2-Line To 4-Line Decoders/Demultiplexers The SN74HCT139DR is a dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments (TI).  

### **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  
- **High-Level Input Voltage (Min)**: 2V  
- **Low-Level Input Voltage (Max)**: 0.8V  
- **Operating Temperature Range**: -40°C to +85°C  
- **Package Type**: SOIC (16-pin)  
- **Output Type**: Standard  
- **Propagation Delay Time**: 18ns (typical at 5V)  
- **Current - Output High, Low**: 4mA, 4mA  
- **Mounting Type**: Surface Mount  

### **Descriptions:**  
The SN74HCT139DR consists of two independent 2-to-4 decoders that accept two binary-weighted inputs (A0, A1) and provide four mutually exclusive active-low outputs (Y0-Y3). Each decoder has an active-low enable input (E), which, when high, disables all outputs.  

### **Features:**  
- **High-Speed CMOS Logic**  
- **Low Power Consumption**  
- **Compatible with TTL Inputs**  
- **Schmitt-Trigger Inputs for Noise Immunity**  
- **Wide Operating Voltage Range**  
- **ESD Protection Exceeds 2000V (HBM)**  

This device is commonly used in address decoding, memory selection, and data routing applications.
