Description and Introduction

7CH DARLINGTON SINK DRIVER The ULN2004AFW is a high-voltage, high-current Darlington transistor array manufactured by Toshiba.  

### **Specifications:**  
- **Configuration:** 7-channel Darlington 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 Type:** SOIC-16 (Surface Mount)  
- **Operating Temperature Range:** -20°C to +85°C  

### **Descriptions and Features:**  
- **Darlington Pair Configuration:** Each channel consists of two NPN transistors in a Darlington pair for high gain.  
- **Integrated Suppression Diodes:** Includes freewheeling diodes for inductive load protection.  
- **High-Voltage and High-Current Capability:** Suitable for driving relays, solenoids, and stepper motors.  
- **TTL/CMOS Compatible Inputs:** Allows direct interfacing with logic circuits.  
- **Common Cathode Clamp Diodes:** Simplifies circuit design for inductive loads.  

This device is commonly used in applications requiring high-current switching, such as motor drivers, LED displays, and relay control circuits.
