Description and Introduction

Dual Monostable Multivibrators With Schmitt-trigger Inputs The SN54221J is a dual monostable multivibrator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** SN54221J  
- **Type:** Dual Monostable Multivibrator  
- **Technology:** TTL (Transistor-Transistor Logic)  
- **Supply Voltage (VCC):** 4.75V to 5.25V (standard TTL levels)  
- **Operating Temperature Range:** -55°C to +125°C (military-grade)  
- **Package:** Ceramic DIP (Dual In-line Package)  
- **Trigger Inputs:** Positive and negative edge-triggered  
- **Output Type:** Standard TTL output  

### **Descriptions and Features:**  
- The SN54221J consists of two independent retriggerable monostable multivibrators.  
- Each multivibrator can be triggered by either a rising or falling edge.  
- Provides a stable output pulse width determined by external timing components (resistor and capacitor).  
- Retriggerable function allows extending the output pulse by reapplying a trigger before the pulse ends.  
- Designed for high-reliability applications, including military and aerospace systems.  
- Features Schmitt-trigger inputs for noise immunity.  

This device is part of the SN54 series, which is the military-grade version of TI's logic ICs, ensuring rugged performance in harsh environments.
