Description and Introduction

1-of-8 Data Selectors/Multiplexers With 3-State Outputs The SN74ALS251N is a 8-input multiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Multiplexer  
- **Number of Circuits:** 1  
- **Number of Inputs:** 8  
- **Output Type:** Tri-State  
- **Voltage Supply:** 4.5V to 5.5V  
- **Operating Temperature:** 0°C to 70°C  
- **Package / Case:** PDIP-16  
- **Mounting Type:** Through Hole

- **High-Level Output Current:** -2.6mA  
- **Low-Level Output Current:** 24mA  

### **Descriptions:**  
The SN74ALS251N is an 8-input digital multiplexer with tri-state outputs. It selects one of eight data inputs (D0-D7) based on the select lines (A, B, C) and provides the selected input at the output (Y) or its complement (W). The output enable (OE) pin controls the tri-state output.  

### **Features:**  
- **8-to-1 Multiplexer Function**  
- **Tri-State Outputs for Bus-Oriented Applications**  
- **Complementary Outputs (Y and W)**  
- **Low Power Consumption (ALS Series)**  
- **Wide Operating Voltage Range (4.5V to 5.5V)**  
- **Fast Switching Speed (12ns typical propagation delay)**  
- **16-Pin DIP Package**  

This device is commonly used in digital systems for data routing, signal selection, and bus interfacing.
