Description and Introduction

Retriggerable monostable multivibrator The SN74LS122NSR is a monostable multivibrator (one-shot) manufactured by Texas Instruments. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Category:** Integrated Circuits (ICs)  
- **Type:** Monostable Multivibrator  
- **Series:** 74LS  
- **Package / Case:** 16-SOIC (0.209", 5.30mm Width)  
- **Operating Temperature:** 0°C to 70°C  
- **Voltage Supply:** 4.75V to 5.25V  
- **Output Type:** Standard  
- **Trigger Type:** Negative, Positive Edge  
- **Number of Circuits:** 1  
- **Propagation Delay Time:** 45 ns (Typical)  
- **Current - Output High, Low:** 400µA, 8mA  

### **Descriptions:**  
- The SN74LS122NSR is a retriggerable/resettable monostable multivibrator designed for precision timing applications.  
- It features both positive and negative edge triggering, along with an internal timing resistor for simplified operation.  
- The device can be retriggered or reset during operation, allowing flexible pulse-width control.  

### **Features:**  
- **Retriggerable/Resettable Operation:** Allows pulse-width extension or early termination.  
- **Internal Timing Resistor:** Eliminates the need for an external resistor in basic applications.  
- **Wide Pulse Width Range:** Adjustable via external components.  
- **Schmitt-Trigger Inputs:** Provides noise immunity on input signals.  
- **Standard Output Drive:** Compatible with TTL logic levels.  

This information is based solely on the device's datasheet and technical documentation.

Description and Introduction

Retriggerable monostable multivibrator The SN74LS122NSR is a monostable multivibrator (one-shot) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Function:** Retriggerable/Resettable Monostable Multivibrator  
- **Number of Circuits:** 1  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Propagation Delay:** Typically 35ns  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** SOIC-16 (NSR)  
- **Output Type:** Standard  
- **Trigger Type:** Positive or Negative Edge  
- **Pulse Width Range:** Adjustable via external components (R and C)  

### **Descriptions:**  
The SN74LS122NSR is a precision monostable multivibrator that generates a controlled output pulse when triggered. It can be retriggered for extended pulse widths and includes a reset function to terminate the pulse early.  

### **Features:**  
- Retriggerable for pulse-width extension  
- Resettable for early pulse termination  
- Adjustable pulse width using external resistor and capacitor  
- Compatible with TTL logic levels  
- Available in a surface-mount SOIC-16 package  

For exact timing calculations, refer to the datasheet for resistor and capacitor selection guidelines.
