- **Output Type:** Push-Pull  
- **High-Level Output Current:** -4 mA  
- **Low-Level Output Current:** 4 mA  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The SN74HCT157D is a high-speed CMOS logic quad 2-input multiplexer. It selects one of two data inputs (A or B) based on the select input (S). It features common select and enable inputs, making it suitable for data routing, signal gating, and parallel-to-serial conversion applications.  

### **Features:**  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **High Noise Immunity:** HCT family provides improved noise margins.  
- **Wide Operating Voltage:** Compatible with 5V systems.  
- **Balanced Propagation Delays:** Ensures consistent performance.  
- **Schmitt-Trigger Inputs:** Allows for slow input transition and better noise rejection.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.  

This device is commonly used in digital systems for data selection, signal routing, and bus interfacing.
