Description and Introduction

FAST CMOS 1-OF-8 DECODER WITH ENABLE The IDT74FCT138CTSO is a 3-to-8 line decoder/demultiplexer manufactured by Integrated Device Technology (IDT). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Technology:** Fast CMOS (FCT)  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input/Output Compatibility:** TTL levels  
- **Propagation Delay:** Typically 5.5 ns  
- **Input Current (Max):** ±1 µA  
- **Output Drive Capability:** 24 mA (sink/source)  
- **Package Type:** SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**
- The IDT74FCT138CTSO is a high-speed, low-power decoder/demultiplexer designed for digital logic applications.  
- It accepts a 3-bit binary input and decodes it into one of eight mutually exclusive outputs (active-low).  
- Features three enable inputs (two active-low and one active-high) for cascading and control flexibility.  

### **Features:**
- **High-Speed Operation:** Optimized for fast signal propagation.  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **TTL-Compatible Inputs/Outputs:** Ensures seamless integration with TTL logic families.  
- **Three Enable Inputs:** Allows easy expansion and control (G1, /G2A, /G2B).  
- **ESD Protection:** Provides robustness against electrostatic discharge.  
- **Wide Operating Voltage Range:** Supports 4.5V to 5.5V operation.  

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