Description and Introduction

QUADRUPLE 1-OF-2 DATA SELECTORS/MULTIPLEXERS The SN74AS157NSR is a quadruple 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Data Selector/Multiplexer  
- **Number of Circuits:** 4  
- **Number of Inputs:** 2  
- **Output Type:** Standard  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** SOP-16  
- **Mounting Type:** Surface Mount  
- **Propagation Delay Time:** 7.5 ns (max)  
- **High-Level Output Current:** -15 mA  
- **Low-Level Output Current:** 48 mA  

### **Descriptions:**  
The SN74AS157NSR is a high-speed TTL logic device that selects one of two data sources based on the select input. It features four independent 2-input multiplexers and is designed for high-performance digital systems.  

### **Features:**  
- **High-Speed Operation:** Optimized for fast switching applications.  
- **Common Select Input:** Single select line controls all four multiplexers.  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V operation.  
- **Low Power Consumption:** Designed for efficient power usage.  
- **Schottky-Clamped Inputs:** Improves noise immunity and switching performance.  
- **Balanced Propagation Delays:** Ensures consistent timing across outputs.  

This device is commonly used in data routing, signal gating, and digital system design.
