Description and Introduction

DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATOR The M74HC123B1R is a dual retriggerable monostable multivibrator manufactured by STMicroelectronics.  

### **Specifications:**  
- **Technology:** High-Speed CMOS (HC)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Propagation Delay:** Typically 15ns at 5V  
- **Input Current:** ±1μA (max)  
- **Output Current:** ±5.2mA (max)  
- **Package:** SO-16  

### **Descriptions:**  
- The M74HC123B1R consists of two independent retriggerable monostable multivibrators.  
- Each multivibrator features both positive (A) and negative (B) edge-triggered inputs.  
- The output pulse width is adjustable using external timing components (resistor and capacitor).  
- It is designed for high noise immunity and low power consumption.  

### **Features:**  
- **Dual Monostable Multivibrators:** Two independent circuits in one package.  
- **Retriggerable Operation:** Allows extending the output pulse by retriggering.  
- **Wide Operating Voltage:** 2V to 6V supply range.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **High Noise Immunity:** CMOS technology ensures robustness.  
- **Direct Reset Input:** Provides immediate termination of the output pulse.
