### **Descriptions:**  
The SN74ALS253DR is a dual 4-input multiplexer with tri-state outputs, designed for high-speed logic applications. It allows two independent 4-line to 1-line data selections, controlled by common select inputs. The tri-state outputs enable bus-oriented applications.  

### **Features:**  
- Dual 4-line to 1-line multiplexers  
- Tri-state outputs for bus interfacing  
- Schottky-clamped for high performance  
- Low power consumption  
- Compatible with TTL inputs  
- Balanced propagation delays  
- ESD protection (up to 2000V)  

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