### **Features:**  
- **Precision Voltage Monitoring:** Monitors VCC with high accuracy (±1.5%).  
- **Adjustable Reset Timeout:** Configurable via an external capacitor.  
- **Wide Operating Voltage Range:** Supports 4.5V to 18V input.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Low Quiescent Current:** Ensures minimal power consumption.  
- **Temperature Stability:** Operates reliably across industrial temperature ranges.  
- **Package Options:** Available in SOIC-8 and PDIP-8 for flexible PCB mounting.  

This information is based solely on the manufacturer's datasheet and technical documentation.
