#### **Descriptions:**  
The SN74AHC157PWR is a high-speed CMOS logic quad 2-input multiplexer. It selects one of two data sources (A or B) based on the select input (S). It is designed for 2 V to 5.5 V operation, making it suitable for mixed-voltage applications.  

#### **Features:**  
- **Low Power Consumption:** Optimized for battery-operated devices  
- **High-Speed Operation:** 10.5 ns max propagation delay at 5 V  
- **Balanced Propagation Delays:** Ensures stable performance  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **Output Drive Capability:** ±8 mA at 5 V  
- **Schmitt-Trigger Inputs:** Improved noise immunity  
- **ESD Protection:** Exceeds JESD 22 standards  
- **TSSOP-16 Package:** Space-saving surface-mount design  

This device is commonly used in data routing, signal switching, and digital systems requiring multiplexing functions.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • 74AHC157PW,118 --: Same AHC-family quad 2-input multiplexer in TSSOP-16, direct functional and pin-compatible replacement with equivalent speed and drive.
  • MC74VHC157DTR2G --: VHC-family quad 2-to-1 multiplexer in TSSOP-16, similar CMOS logic characteristics and pinout, suitable drop-in alternative.
  • 74VHC157FT --: VHC quad 2-input multiplexer in TSSOP-16, comparable propagation delay and drive current, pin-compatible substitute.
  • SN74AHCT157PWR --: Same TI AHCT series quad multiplexer with TTL-compatible inputs, same pinout and package, suitable when input threshold compatibility is needed.
  • 74AHC157PW-Q100,118 --: Automotive-qualified quad 2-input multiplexer in TSSOP-16, same function and package, suitable as a higher-reliability drop-in.
