Description and Introduction

Dual Retriggerable Monostable Multivibrators The SN74LV123APW is a dual retriggerable monostable multivibrator manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Type:** Monostable Multivibrator  
- **Number of Circuits:** 2  
- **Logic Family:** LV (Low-Voltage)  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Propagation Delay Time:** 18 ns (typical) at 5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-16  
- **Output Type:** Push-Pull  
- **Trigger Type:** Negative and Positive Edge  

### **Descriptions:**  
- The SN74LV123APW is a dual retriggerable monostable multivibrator designed for low-voltage operation.  
- It provides two independent one-shot circuits with both positive and negative edge-triggered inputs.  
- The output pulse duration can be controlled by external timing components (resistor and capacitor).  
- It is suitable for applications requiring precise timing, such as pulse generation and delay circuits.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **Retriggerable Operation:** Allows extending the output pulse by retriggering.  
- **Clear Input:** Each one-shot has an active-low clear input for immediate termination of the output pulse.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Schmitt-Trigger Inputs:** Provides noise immunity for reliable triggering.  
- **Push-Pull Outputs:** Ensures strong drive capability.  

This information is strictly factual and based on the manufacturer's datasheet.
