Description and Introduction

Dual 2-Line To 4-Line Decoders/Demultiplexers The SN74HC139PWR is a dual 2-line to 4-line decoder/demultiplexer manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** SN74HC139PWR  
- **Package:** TSSOP-16  
- **Technology:** High-Speed CMOS (HC)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Input Type:** CMOS  
- **Output Type:** CMOS  
- **Propagation Delay (Max):** 19 ns at 5V  
- **Current - Output High, Low:** ±5.2 mA  
- **Number of Circuits:** 2  
- **Number of Input Lines:** 2 (per decoder)  
- **Number of Output Lines:** 4 (per decoder)  

### **Descriptions:**
- The SN74HC139PWR is a dual 2-to-4 line decoder/demultiplexer designed for high-performance digital systems.  
- 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 (E) input that, when high, forces all outputs to a high state.  
- It can be used as a 1-to-4 demultiplexer when the enable input is used as the data input.  

### **Features:**
- **Dual Decoder/Demultiplexer:** Contains two independent 2-to-4 decoders in a single package.  
- **Low Power Consumption:** Typical ICC of 2 µA (max).  
- **High Noise Immunity:** CMOS technology ensures robust operation.  
- **Wide Operating Voltage:** Supports 2V to 6V, making it compatible with TTL and other logic families.  
- **Balanced Propagation Delays:** Ensures reliable timing in digital circuits.  
- **Output Drive Capability:** Can drive up to 10 LSTTL loads.  
- **ESD Protection:** Exceeds 2000 V per JESD 22.
