Description and Introduction

RAD HARD DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATOR The M54HC4538 is a high-speed CMOS dual retriggerable monostable multivibrator manufactured by STMicroelectronics (ST).  

### **Key Specifications:**  
- **Supply Voltage Range:** 2V to 6V  
- **High Noise Immunity:** CMOS technology ensures robust performance  
- **Low Power Consumption:** Typical quiescent current of 4µA at 5V  
- **Operating Temperature Range:** -55°C to +125°C (Military grade)  
- **Propagation Delay:** Typically 40ns at 5V  
- **Output Current:** ±4mA at 5V  

### **Descriptions:**  
- **Dual Monostable Multivibrator:** Contains two independent retriggerable/resettable monostable circuits  
- **Retriggerable Function:** Allows pulse width extension by retriggering during operation  
- **Direct Reset Capability:** Active-low reset pin for immediate termination of output pulse  
- **Schmitt Trigger Inputs:** Ensures noise immunity on trigger inputs  

### **Features:**
