Description and Introduction

Quadruple 2-Line To 1-Line Data Selectors/Multiplexers 16-SSOP -40 to 85 The SN74HC157DBR is a high-speed CMOS logic quadruple 2-input multiplexer manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** Multiplexer  
- **Number of Circuits:** 4  
- **Number of Inputs:** 2 per multiplexer  
- **Output Type:** Non-Inverted  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SSOP (DBR)  
- **Package / Case:** SSOP-16  
- **Propagation Delay Time:** 13 ns (typical at 5V)  
- **High-Level Output Current:** -5.2 mA  
- **Low-Level Output Current:** 5.2 mA  

### **Descriptions:**  
The SN74HC157DBR is a 4-bit 2-input multiplexer that selects one of two data sources based on the select input. It features common select and enable inputs, making it suitable for data routing and selection in digital systems.  

### **Features:**  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **Wide Operating Voltage:** Supports 2V to 6V operation.  
- **High Noise Immunity:** Typical of CMOS devices.  
- **Balanced Propagation Delays:** Ensures consistent performance.  
- **Common Select and Enable Inputs:** Simplifies control logic.  
- **Schmitt-Trigger Inputs:** Improves noise rejection on select lines.  

This device is commonly used in data selection, signal routing, and digital switching applications.

Application Scenarios & Design Considerations

Quadruple 2-Line To 1-Line Data Selectors/Multiplexers 16-SSOP -40 to 85

Alternative Part Number

  • 74HC157D --: Quad 2-to-1 multiplexer with the same HC logic family and function, offered in a SOIC package by a major logic supplier; a direct functional equivalent to the TI part.
  • MC74HC157ADG --: Pin-compatible quad 2-input multiplexer in the 74HC series from ON Semiconductor, widely available and electrically equivalent for most designs.
  • CD74HC157E --: Same HC157 multiplexer function from TI in a different package (PDIP), useful when a through-hole or alternate footprint is acceptable.
