Description and Introduction

BIPOLAR DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC 8CH DARLINGTON SINK DRIVER The ULN2803AP is a high-voltage, high-current Darlington transistor array manufactured by Texas Instruments.  

### **Specifications:**  
- **Type:** Darlington Transistor Array  
- **Number of Channels:** 8  
- **Output Current per Channel:** 500 mA (max)  
- **Output Voltage (Max):** 50 V  
- **Input Voltage (Max):** 30 V  
- **Input Compatibility:** TTL, CMOS, PMOS  
- **Package Type:** PDIP-18 (Plastic Dual In-line Package)  
- **Operating Temperature Range:** -20°C to +85°C  
- **Features Common Cathode Clamp Diodes for Inductive Loads**  

### **Descriptions:**  
The ULN2803AP consists of eight NPN Darlington pairs with high-voltage and high-current capability. It is designed for interfacing between low-level logic circuits (such as TTL, CMOS, or PMOS) and high-current/high-voltage loads like relays, lamps, or solenoids.  

### **Features:**  
- **High-Voltage Outputs (50V max)**  
- **High-Current Darlington Sinks (500mA per channel)**  
- **Inputs Compatible with Various Logic Types (TTL, CMOS, PMOS)**  
- **Clamp Diodes for Inductive Load Protection**  
- **Wide Operating Temperature Range**  
- **Simplifies Microcontroller/Logic to High-Power Load Interfaces**  

The ULN2803AP is commonly used in applications such as relay drivers, motor controls, LED displays, and other high-power switching circuits.
