### **Descriptions:**  
The ULQ2801A is a monolithic high-voltage, high-current Darlington transistor array designed for interfacing between low-level logic circuits and high-power loads. It integrates eight Darlington pairs with common emitters, each capable of driving loads up to 500 mA. The device is suitable for relay, solenoid, lamp, and motor driving applications.  

### **Features:**  
- **Eight Darlington Channels** with common emitters  
- **High-Voltage Outputs** (50 V max)  
- **TTL/CMOS-Compatible Inputs** (5 V logic)  
- **Integrated Suppression Diodes** for inductive loads  
- **High Current Capability** (500 mA per channel)  
- **Wide Operating Temperature Range**  
- **Reliable and Robust Design** for industrial applications  

For detailed electrical characteristics, refer to the official STMicroelectronics datasheet.
