Description and Introduction

1-of-8 Data Selectors/Multiplexers The SN74AS151NSR is a 1-of-8 data selector/multiplexer manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** Multiplexer  
- **Number of Circuits:** 1  
- **Number of Inputs:** 8  
- **Output Type:** Single-Ended  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-16  
- **Mounting Type:** Surface Mount  
- **Propagation Delay Time:** 8.5ns (typical)  
- **Current - Output High, Low:** 15mA, 48mA  

### **Descriptions:**  
The SN74AS151NSR is a high-speed TTL logic 8-input multiplexer that selects one of eight data inputs (D0-D7) based on three select lines (A, B, C). It features complementary outputs (Y and W) for flexibility in logic design.  

### **Features:**  
- **High-Speed Operation:** Optimized for fast switching applications.  
- **Wide Operating Voltage:** Supports standard 5V logic levels.  
- **Complementary Outputs:** Provides both true (Y) and inverted (W) outputs.  
- **Strobe Input:** An enable (G) input allows for cascading multiple devices.  
- **Low Power Consumption:** Designed for efficient power usage.

Application Scenarios & Design Considerations

1-of-8 Data Selectors/Multiplexers

Alternative Part Number

  • CD74ACT151E --: 8-input multiplexer with complementary outputs in the same function class; ACT logic offers comparable speed with lower power and is a common drop-in for AS-series designs.
  • MC74ACT151N --: Pin-compatible 8-line to 1-line data selector/multiplexer from a different series and vendor, providing a second source with similar AC characteristics.
  • 74ACT151PC --: Standard 74ACT151 multiplexer in a DIP package; widely available alternate logic family that matches the AS151 function and timing closely.
  • CD74ACT151M96 --: 8-to-1 multiplexer with complementary outputs in SOIC, functionally equivalent to the SN74AS151 with compatible pinout and logic function.
  • MC74ACT151DR2G --: 8-input multiplexer in SOIC package offering similar function and ACT logic family compatibility for direct replacement.
  • 74ACT151SC --: 8-to-1 data selector/multiplexer in SOIC with equivalent logic function and pin configuration.
