Description and Introduction

Quadruple 2-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs The SN74HC257N is a quad 2-input multiplexer with 3-state outputs, manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** Multiplexer  
- **Number of Circuits:** 4  
- **Number of Inputs:** 2 per multiplexer  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Propagation Delay:** Typically 12ns at 5V  
- **Current - Output High, Low:** ±7.8mA  
- **Package / Case:** PDIP-16  
- **Mounting Type:** Through Hole  

### **Descriptions:**  
The SN74HC257N is a high-speed CMOS logic device that selects one of two data inputs (A or B) based on the select (S) input. The outputs are enabled or disabled via the output enable (OE) input, allowing for bus-oriented applications.  

### **Features:**  
- **3-State Outputs:** Allows for bus sharing  
- **High-Speed Operation:** Optimized for performance  
- **Wide Operating Voltage:** 2V to 6V  
- **Low Power Consumption:** CMOS technology  
- **Balanced Propagation Delays:** Ensures signal integrity  
- **Common Output Enable (OE) Control:** Simplifies system design  

This device is commonly used in data routing, signal selection, and bus interface applications.
