Description and Introduction

High-Voltage, High-Current Darlington Transistor Arrays The ULN2003APWR is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Configuration:** 7-channel Darlington transistor array  
- **Output Voltage:** 50V (max)  
- **Output Current (per channel):** 500mA (max)  
- **Input Voltage (Logic Compatible):** 5V (TTL, CMOS)  
- **Package:** TSSOP-16  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features Built-in Clamp Diodes:** Yes (for inductive load protection)  

### **Descriptions and Features:**  
- **High-Voltage, High-Current Driver:** Designed to drive relays, solenoids, stepper motors, and other high-power loads.  
- **Integrated Suppression Diodes:** Allows direct interfacing with inductive loads without external protection diodes.  
- **TTL/CMOS Compatible Inputs:** Works with 5V logic levels, making it suitable for microcontroller interfacing.  
- **Open-Collector Outputs:** Each channel can sink up to 500mA.  
- **Cascadable:** Multiple ULN2003s can be connected for higher current handling.  
- **Applications:** Relay drivers, lamp drivers, display drivers (LED), logic buffers, and motor control circuits.  

This device is widely used in industrial and automotive applications due to its robustness and ease of integration.
