Description and Introduction

High-Voltage, High-Current Darlington Transistor Array The ULN2004ADR is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Configuration:** 7-channel Darlington transistor array  
- **Output Current per Channel:** 500 mA (max)  
- **Output Voltage (Collector-Emitter):** 50 V (max)  
- **Input Voltage (Base-Emitter):** 30 V (max)  
- **Input Compatibility:** TTL, CMOS, PMOS  
- **Package:** SOIC-16  
- **Operating Temperature Range:** -20°C to +85°C  
- **Features Built-in Suppression Diodes:** Yes (for inductive loads)  

### **Descriptions and Features:**  
- Designed for interfacing between low-level logic and high-power loads.  
- Each channel includes a Darlington pair with common-emitter outputs.  
- Integrated clamp diodes for switching inductive loads.  
- Suitable for relay drivers, lamp drivers, display drivers (LED, incandescent), and motor controllers.  
- Inputs are pinned opposite outputs for easy PCB layout.  
- High noise immunity and simplified circuit design.  

This device is widely used in industrial and automotive applications for driving high-current loads from logic-level signals.
