Description and Introduction

Dual monostable multivibrators with Schmitt-trigger inputs The SN74221N is a dual monostable multivibrator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Propagation Delay:** Typically 45 ns  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP (Plastic Dual In-Line Package)  
- **Pin Count:** 16  
- **Output Current:** ±8 mA (High), 16 mA (Low)  
- **Trigger Inputs:** Compatible with TTL and CMOS logic levels  

### **Descriptions:**  
- The SN74221N is designed to generate precise output pulses of a defined duration when triggered.  
- Each of the two monostable multivibrators in the IC can operate independently.  
- It features Schmitt-trigger inputs for noise immunity and retriggerable functionality.  

### **Features:**  
- **Dual Monostable Multivibrator:** Two independent one-shot circuits in a single package.  
- **Wide Operating Voltage Range:** Compatible with standard 5V TTL logic.  
- **Schmitt-Trigger Inputs:** Ensures clean transitions and noise rejection.  
- **Retriggerable Operation:** Allows extending the output pulse by reapplying a trigger.  
- **Direct Clear Input:** Provides immediate termination of the output pulse.
