Description and Introduction

HIGH-VOLTAGE, HIGH-CURRENT DARLINGTON ARRAY The ULN7003A is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Configuration:** 7-channel Darlington array  
- **Output Voltage:** Up to 50V  
- **Output Current:** 500mA per channel (600mA peak)  
- **Input Voltage Compatibility:** 3V to 5V logic  
- **Input Current:** 2.5mA per channel (typical)  
- **Clamp Diodes:** Included for inductive load protection  
- **Package:** 16-pin DIP (Dual In-line Package)  

### **Descriptions & Features:**  
- Designed for interfacing between low-voltage digital circuits and high-power loads.  
- Each channel consists of a Darlington pair with high current gain.  
- Built-in suppression diodes for switching inductive loads.  
- Common-cathode clamp diodes for back EMF protection.  
- Suitable for driving relays, lamps, solenoids, and stepper motors.  
- Compatible with TTL, CMOS, and PMOS logic levels.  
- High noise immunity for industrial applications.  

This device is commonly used in applications requiring high-power switching from low-power control signals.
