Description and Introduction

Quadruple 2-Line to 1-Line Data Selectors/Multiplexers With 3-State Outputs The SN74AS258N is a quad 2-input multiplexer with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology Family:** AS (Advanced Schottky)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Number of Channels:** 4  
- **Output Type:** 3-State  
- **Propagation Delay (Max):** 9 ns  
- **Input Type:** TTL-Compatible  
- **Package Type:** PDIP (Plastic Dual-In-Line Package)  
- **Pin Count:** 16  

### **Descriptions:**  
The SN74AS258N is a high-speed, low-power quad 2-input multiplexer with 3-state outputs. It selects one of two data inputs (A or B) based on the select input (S) and provides the selected data to the output (Y). The outputs can be placed in a high-impedance state using the output enable (OE) input.  

### **Features:**  
- **Quad 2-Input Multiplexer:** Four independent multiplexers in a single package.  
- **3-State Outputs:** Allows for bus-oriented applications.  
- **High-Speed Operation:** Optimized for performance with fast propagation delay.  
- **TTL-Compatible Inputs:** Ensures compatibility with standard TTL logic levels.  
- **Low Power Consumption:** Designed for efficient power usage.  
- **Wide Operating Voltage Range:** Supports standard 5V logic systems.  

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

Application Scenarios & Design Considerations

Quadruple 2-Line to 1-Line Data Selectors/Multiplexers With 3-State Outputs

Alternative Part Number

  • 74F258PC --: Same 74-series quad 2-input multiplexer with 3-state outputs in a DIP-16 package; F-series offers comparable speed and is a common drop-in substitute.
  • MC74ACT258N --: Quad 2-input multiplexer with 3-state outputs in DIP-16; ACT logic family provides similar function and TTL-compatible inputs.
  • CD74HCT258E --: HCT-family quad 2-input multiplexer with 3-state outputs in DIP-16, offering equivalent logic function with TTL-compatible input thresholds.
