Description and Introduction

RETRIGGERABLE MONOSTABLE MULTIVIBRATORS The SN74LS123N is a dual retriggerable monostable multivibrator manufactured by Texas Instruments (ON Semiconductor is not the manufacturer).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Circuits:** 2  
- **Propagation Delay Time:** 45 ns (typical)  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP-16 (Plastic Dual In-line Package)  
- **Output Type:** Standard  

### **Descriptions:**  
The SN74LS123N features two independent retriggerable monostable multivibrators, each capable of generating precise output pulses. The pulse width can be adjusted using external timing components (resistor and capacitor).  

### **Features:**  
- **Retriggerable Operation:** Allows pulse width extension by retriggering before the initial pulse ends.  
- **Clear Input:** Provides immediate termination of the output pulse.  
- **Wide Range of Pulse Widths:** Adjustable via external RC components.  
- **Direct Replacement for 74123:** Compatible with older TTL logic.  
- **Low Power Consumption:** Typical power dissipation of 45 mW.  

This information is based on Texas Instruments' datasheet for the SN74LS123N.
