Description and Introduction

High Speed CMOS Logic Dual Retriggerable Monostable Multivibrators with Reset The CD74HC123 is a dual retriggerable monostable multivibrator manufactured by Harris Semiconductor. Key specifications include:  

- **Supply Voltage Range**: 2V to 6V  
- **High-Speed Operation**: Compatible with HC logic family  
- **Output Current**: ±25mA  
- **Propagation Delay**: Typically 13ns (at 5V)  
- **Retriggerable Feature**: Allows extension of output pulse  
- **Operating Temperature Range**: -55°C to +125°C  
- **Package Options**: DIP, SOIC, and other surface-mount packages  

This device is designed for precision timing applications with adjustable pulse widths via external resistors and capacitors.  

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