Description and Introduction

High Speed CMOS Logic Dual Monostable Multivibrators with Reset The CD74HCT221E is a dual monostable multivibrator (one-shot) manufactured by Texas Instruments (TI). Here are its key specifications:

- **Technology**: High-Speed CMOS (HCT)  
- **Supply Voltage Range**: 4.5V to 5.5V  
- **Propagation Delay**: Typically 28 ns at 5V  
- **Output Current**: ±4 mA (at 5V)  
- **Operating Temperature Range**: -55°C to +125°C  
- **Package**: 16-pin PDIP (Plastic Dual In-Line Package)  
- **Input Compatibility**: TTL-level inputs  
- **Trigger Modes**: Positive or negative edge-triggered  
- **Retriggerable**: No (non-retriggerable)  
- **Power Dissipation**: 500 mW (max)  

This device is designed for precision timing applications and features Schmitt-trigger inputs for noise immunity.
