Description and Introduction

Quadruple 2-Line To 1-Line Data Selector/Multiplexer With 3-State Outputs The SN74LVC257ANSR is a quad 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Data Selector/Multiplexer  
- **Number of Channels:** 4  
- **Input Type:** Single-Ended  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 1.65V to 3.6V  
- **High-Level Output Current:** -24mA  
- **Low-Level Output Current:** 24mA

- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16 (NSR)  

### **Descriptions:**  
- The SN74LVC257ANSR is a high-speed CMOS logic device that selects one of two data inputs (A or B) based on the select (S) input.  
- It features 3-state outputs for bus-oriented applications.  
- Designed for 1.65V to 3.6V VCC operation, making it suitable for low-voltage systems.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **Wide Operating Voltage Range:** Supports mixed-voltage applications.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **Balanced Propagation Delays:** Ensures consistent performance.  
- **ESD Protection:** Exceeds 2000V per JESD 22.

Application Scenarios & Design Considerations

Quadruple 2-Line To 1-Line Data Selector/Multiplexer With 3-State Outputs

Alternative Part Number

  • 74LVC257APW,118 --: Quad 2-input multiplexer with 3-state outputs in the same LVC logic family, available in TSSOP package as a close functional and electrical equivalent.
  • MC74LCX257DTR2G --: LCX-series quad 2-input multiplexer with 3-state outputs, comparable low-voltage CMOS performance and pin-compatible function.
  • 74LVC257ADB,112 --: Same LVC 2-input multiplexer function in SSOP package, suitable drop-in alternative when package footprint allows.
  • 74LVC257AD,118 --: SOIC-packaged quad 2-input multiplexer from the LVC family, same logic function and voltage range, alternate package option.
