Description and Introduction

3-Line To 8-Line Decoder / Demultiplexer The SN74AHC138N is a 3-to-8 line decoder/demultiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Decoder/Demultiplexer  
- **Number of Input Lines:** 3  
- **Number of Output Lines:** 8 (active-low)  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High Noise Immunity:** CMOS technology  
- **Low Power Consumption:** Typical ICC of 1 µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** PDIP-16 (Plastic Dual In-Line Package)  
- **Propagation Delay:** Typically 7.5 ns at 5 V  
- **Output Drive Capability:** ±8 mA at 5 V  

### **Descriptions:**  
The SN74AHC138N 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 reduce the need for external gates.  

### **Features:**  
- **3-to-8 Line Decoding:** Converts 3-bit input into 8 active-low outputs.  
- **Multiple Enable Inputs:** Two active-low (G1, G2A, G2B) and one active-high (G1) for easy expansion.  
- **Wide Operating Voltage:** Supports 2 V to 5.5 V operation.  
- **Balanced Propagation Delays:** Ensures stable performance.  
- **Low Power Consumption:** Suitable for battery-operated applications.  
- **High Noise Immunity:** CMOS design reduces susceptibility to noise.  
- **Latch-Up Performance Exceeds 250 mA:** Per JESD 17.  

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