### **Descriptions:**  
The SN74HCT138DR is a high-speed CMOS logic device that decodes three binary address inputs (A0, A1, A2) into one of eight mutually exclusive outputs (Y0-Y7). It features three enable inputs (two active-low and one active-high) to simplify cascading and system control.  

### **Features:**  
- **3-to-8 Line Decoding/Demultiplexing**  
- **Active-Low Outputs**  
- **Multiple Enable Inputs for Easy Expansion**  
- **Low Power Consumption**  
- **Compatible with TTL Inputs**  
- **Schmitt-Trigger Inputs for Noise Immunity**  
- **Wide Operating Voltage Range (4.5V to 5.5V)**  

This device is commonly used in memory address decoding, data routing, and other digital logic applications.
