Description and Introduction

High Speed CMOS Logic 3-to-8 Line Decoder/Demultiplexer Inverting and Non-Inverting The CD74HCT138M is a high-speed CMOS logic 3-to-8 line decoder/demultiplexer manufactured by Texas Instruments (TI). Here are its key specifications:

- **Logic Type**: Decoder/Demultiplexer  
- **Number of Input Lines**: 3  
- **Number of Output Lines**: 8 (active-low)  
- **Supply Voltage Range**: 4.5V to 5.5V (HCT family)  
- **High-Level Input Voltage (Min)**: 2V  
- **Low-Level Input Voltage (Max)**: 0.8V  
- **Operating Temperature Range**: -55°C to +125°C  
- **Propagation Delay (Max)**: 38 ns at 4.5V  
- **Current - Output High, Low**: 4mA, 4mA  
- **Package / Case**: SOIC-16  
- **Mounting Type**: Surface Mount  

The device features three enable inputs (two active-low and one active-high) for cascading applications. It is designed for high-noise immunity and low power consumption typical of CMOS technology while maintaining compatibility with TTL input/output levels.  

For detailed electrical characteristics, refer to the official Texas Instruments datasheet.
