Description and Introduction

Quadruple 2-Line To 1-Line Data Selectors / Multiplexers The SN74AHC157PW is a quad 2-input multiplexer manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Technology Family:** AHC (Advanced High-Speed CMOS)  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Number of Channels:** 4  
- **Input Type:** Schmitt-Trigger  
- **Output Type:** Push-Pull  
- **Propagation Delay:** 7.5 ns (typical at 5 V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-16  
- **Logic Function:** Multiplexer  

### **Descriptions:**  
- The SN74AHC157PW is a high-speed CMOS logic device that selects one of two data inputs based on the select input.  
- It features low power consumption and high noise immunity.  
- Suitable for applications requiring data routing or signal switching.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **Wide Operating Voltage:** Supports 2 V to 5.5 V.  
- **High Noise Immunity:** Ensures reliable operation in noisy environments.  
- **Schmitt-Trigger Inputs:** Allows for slow input transition and better noise rejection.  
- **Balanced Propagation Delays:** Ensures consistent performance.  
- **ESD Protection:** Exceeds 2000 V per JESD 22.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Quadruple 2-Line To 1-Line Data Selectors / Multiplexers

Alternative Part Number

  • MC74VHC157DTR2G --: Quad 2-input multiplexer with same AHC-speed logic family and TSSOP package, pin-compatible function and widely available as a direct second source.
  • 74AHC157PW,118 --: Same AHC157 function in TSSOP-16 package from an established logic supplier, electrically equivalent and drop-in compatible.
  • CD74HC157M96 --: HC-family quad 2-input multiplexer from the same manufacturer with similar speed and drive, usable when slight timing differences are acceptable.
  • 74AHC157PW-Q100,118 --: Automotive-qualified AHC quad multiplexer in TSSOP-16 offering the same logic function and pinout, usable where higher reliability grades are acceptable.
