Description and Introduction

Dual 2-Line To 4-Line Decoder/Demultiplexer The SN74LVC139A is a dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 1.65 V to 3.6 V  
- **High-Speed Operation:** tpd = 4.3 ns (max) at 3.3 V  
- **Low Power Consumption:** ICC = 10 µA (max)  
- **Inputs Accept Voltages up to 5.5 V**  
- **Output Drive Capability:** ±24 mA at 3.3 V  
- **Latch-Up Performance Exceeds 250 mA per JESD 17**

  - 200-V Machine Model (A115-A)  
  - 1000-V Charged-Device Model (C101)  

### **Description:**  
The SN74LVC139A is designed for high-performance memory-decoding or data-routing applications requiring very short propagation delay times. It features two independent 2-to-4 decoders with common active-low enable inputs. Each decoder accepts two binary-weighted inputs (A0, A1) and provides four mutually exclusive active-low outputs (Y0–Y3).  

### **Features:**  
- **Dual 2-to-4 Line Decoder/Demultiplexer**  
- **Operates from 1.65 V to 3.6 V**  
- **5-V Tolerant Inputs**  
- **Supports Mixed-Mode Voltage Operation**  
- **Available in Multiple Package Options (SOIC, TSSOP, VSSOP, PDIP)**  
- **Ioff Supports Partial-Power-Down Mode Operation**  

This device is suitable for applications in industrial, computing, and communication systems.
