Description and Introduction

DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATOR The **TC74HC123AFN** is a dual retriggerable monostable multivibrator manufactured by **TOSHIBA**.  

### **Key Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Number of Circuits:** 2 (Dual)  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V

Description and Introduction

DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATOR The TC74HC123AFN is a dual retriggerable monostable multivibrator manufactured by Toshiba. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage (VCC):** 2V to 6V  
- **High-Level Input Voltage (VIH):** 3.15V (min) at VCC = 4.5V  
- **Low-Level Input Voltage (VIL):** 1.35V (max) at VCC = 4.5V  
- **High-Level Output Current (IOH):** -5.2mA (min) at VCC = 4.5V  
- **Low-Level Output Current (IOL):** 5.2mA (min) at VCC = 4.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin plastic DIP (FN)  

### **Description:**  
The TC74HC123AFN is a high-speed CMOS logic IC that contains two independent retriggerable monostable multivibrators. It is designed for pulse-width control in timing applications and can be triggered by either the positive or negative edge of an input pulse.  

### **Features:**  
- **Retriggerable Operation:** Allows the output pulse width to be extended by retriggering.  
- **Edge-Triggered Inputs:** Can be triggered by rising or falling edges.  
- **Wide Operating Voltage Range:** 2V to 6V.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **High Noise Immunity:** Typical of HC-series CMOS devices.  
- **Output Drive Capability:** Can drive up to 10 LSTTL loads.  
- **Pin-Compatible with 74LS123:** Can be used as a drop-in replacement in some applications.  

This information is strictly factual and derived from Ic-phoenix technical data files.
