Description and Introduction

DUAL MONOSTABLE MULTIVIBRATORS WITH SCHMITT-TRIGGER INPUTS The SN74LS221DB is a dual monostable multivibrator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** Dual Monostable Multivibrator  
- **Package Type:** SOIC (DB)  
- **Number of Circuits:** 2  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Propagation Delay:** Typically 35ns  
- **Output Current:** ±8mA  
- **Trigger Type:** Positive or Negative Edge  

### **Descriptions:**  
The SN74LS221DB features two independent monostable multivibrators that can be triggered by either a positive or negative edge. Each multivibrator has separate controls for pulse width adjustment via external resistors and capacitors.  

### **Features:**  
- **Dual Monostable Multivibrators:** Two independent circuits in one package.  
- **Adjustable Pulse Width:** Determined by external RC components.  
- **Retriggerable Operation:** Allows for extending the output pulse.  
- **Schottky-Clamped Inputs:** Ensures fast switching and noise immunity.  
- **Wide Operating Voltage Range:** Compatible with standard TTL levels.  
- **Low Power Consumption:** Typical of LS series logic.  

This device is commonly used in timing applications, pulse generation, and signal delay circuits.
