Description and Introduction

RETRIGGERABLE MONOSTABLE MULTIVIBRATORS The SN54122 is a monostable multivibrator (one-shot) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage (VCC):** 4.5V to 5.5V (standard TTL levels)  
- **Propagation Delay:** Typically 35 ns  
- **Output Current (High):** -800 µA  
- **Output Current (Low):** 16 mA  
- **Operating Temperature Range:** -55°C to +125°C (military-grade)  
- **Package Options:** Ceramic Dual-In-Line (DIP)  

### **Descriptions:**  
- The SN54122 is a retriggerable monostable multivibrator with Schmitt-trigger inputs.  
- It can be triggered by either a rising or falling edge.  
- The output pulse width is determined by external timing components (resistor and capacitor).  
- It features a clear input for immediate termination of the output pulse.  

### **Features:**  
- **Retriggerable Operation:** Allows extending the output pulse by retriggering before the pulse ends.  
- **Schmitt-Trigger Inputs:** Provides noise immunity on input signals.  
- **Adjustable Pulse Width:** Timing is set via external resistor (R) and capacitor (C).  
- **Military Temperature Range:** Suitable for harsh environments.  

This device is part of TI’s 5400-series logic family, designed for high-reliability applications.
