Description and Introduction

FAST CMOS 1-OF-8 DECODER WITH ENABLE The IDT74FCT138TQ is a 3-to-8 line decoder/demultiplexer manufactured by IDT (Integrated Device Technology). 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-compatible inputs and outputs  
- **Propagation Delay:** Typically 5.5 ns (max 8.5 ns)  
- **Power Dissipation:** Low power CMOS design  
- **Package Type:** TSSOP (Thin Shrink Small Outline Package)  

### **Descriptions:**  
- The IDT74FCT138TQ is a high-speed, low-power decoder/demultiplexer.  
- It accepts a 3-bit binary address input and decodes it to one of eight mutually exclusive outputs.  
- An enable input (G1, G2A, G2B) allows for cascading multiple devices.  

### **Features:**  
- **High-Speed Operation:** Optimized for performance in high-speed systems.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Three Enable Inputs:** Allows for easy expansion and control.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with TTL logic levels.  
- **Balanced Propagation Delays:** Minimizes signal skew.  
- **ESD Protection:** Provides robustness against electrostatic discharge.  

This device is commonly used in memory addressing, data routing, and logic function generation in digital systems.  

(Note: For exact performance metrics, always refer to the official datasheet.)
