### **Descriptions:**  
- The TC74ACT138FN 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) for flexible control.  
- Suitable for memory address decoding and data routing applications.  

### **Features:**  
- **3-to-8 Line Decoding:** Converts 3-bit binary input to 8-line output.  
- **Demultiplexing Capability:** Can function as a 1-to-8 demultiplexer.  
- **High-Speed Operation:** Optimized for fast switching performance.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V operation.  
- **Schmitt Trigger Inputs:** Provides noise immunity on control inputs.  
- **Compatible with TTL Levels:** Inputs are TTL-compatible.  

This device is commonly used in digital systems for address decoding, data routing, and signal demultiplexing.
