Description and Introduction

1-OF-8 Decoder/ Demultiplexer The SN74LS138MEL is a 3-to-8 line decoder/demultiplexer manufactured by ON Semiconductor.  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** 3-to-8 Line Decoder/Demultiplexer  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** SOIC-16  
- **Number of Inputs:** 3 (A, B, C)  
- **Number of Outputs:** 8 (Y0-Y7, active-low)  
- **Enable Inputs:** 3 (G1 active-high, G2A and G2B active-low)  
- **Propagation Delay (max):** 32 ns  
- **Power Dissipation (max):** 93 mW  

### **Descriptions:**  
The SN74LS138MEL decodes three binary address inputs (A, B, C) into one of eight mutually exclusive outputs (Y0-Y7). It features three enable inputs (G1, G2A, G2B) that must be in the correct state (G1 high, G2A and G2B low) for proper operation.  

### **Features:**  
- **Active-Low Outputs:** All outputs are low when selected.  
- **Multiple Enable Inputs:** Allows for easy expansion in larger decoder configurations.  
- **Schottky-Clamped:** Improves switching speed and reduces power consumption.  
- **Wide Operating Voltage:** Compatible with standard TTL levels.  
- **Applications:** Memory decoding, data routing, and address selection in digital systems.
