Description and Introduction

High Speed CMOS Logic 3-to-8 Line Decoder Demultiplexer Inverting and Non-Inverting The CD74HCT238E is a high-speed CMOS logic 3-to-8 line decoder/demultiplexer manufactured by **HARRIS** (now part of Intersil). Key specifications include:  

- **Logic Family**: HCT (High-Speed CMOS, TTL-compatible)  
- **Supply Voltage Range**: 4.5V to 5.5V  
- **Operating Temperature Range**: -55°C to +125°C  
- **Input Levels**: TTL-compatible (2V min for HIGH, 0.8V max for LOW)  
- **Output Drive Capability**: 10 LSTTL loads  
- **Propagation Delay**: Typically 17 ns at 5V  
- **Package**: 16-pin PDIP (Plastic Dual In-Line Package)  
- **Features**: Three enable inputs (two active LOW, one active HIGH) for flexible control  

This device is designed for decoding or demultiplexing applications in digital systems.  

(Note: HARRIS Semiconductor was acquired by Intersil, which was later acquired by Renesas Electronics.)
